The "small" argument to do_sys_ftruncate indicates if > 32-bit size
should be reject, but all the arch-specific compat ftruncate64
implementations get this wrong. Merge do_sys_ftruncate and
ksys_ftruncate, replace the integer as boolean small flag with a
descriptive one about LFS semantics, and use it correctly in the
architecture-specific ftruncate64 implementations.

The symlink name was previously duplicated using an explicit kmalloc()
followed by strcpy(), which is deprecated [1]. Replace this open-coded
string duplication with kstrdup(), which allocates and copies the
symlink name with a single helper function.
Remove the local variable 'size' and set 'i_size' directly using
strlen(cp), which is equivalent to the previous value of 'size'.
This simplifies the code, uses common string-handling helpers, and
removes the deprecated use of strcpy().

mb_cache_destroy() calls shrinker_free() and then frees all cache
entries and the cache itself, but it does not cancel the pending
c_shrink_work work item first.
If mb_cache_entry_create() schedules c_shrink_work via schedule_work()
and the work item is still pending or running when mb_cache_destroy()
runs, mb_cache_shrink_worker() will access the cache after its memory
has been freed, causing a use-after-free.
This is only reachable by a privileged user (root or CAP_SYS_ADMIN)
who can trigger the last put of a mounted ext2/ext4/ocfs2 filesystem.
Cancel the work item with cancel_work_sync() before calling
shrinker_free(), ensuring the worker has finished and will not be
rescheduled before the cache is torn down.

omfs_fill_super() rejects oversized s_sys_blocksize values (> PAGE_SIZE),
but it does not reject values smaller than OMFS_DIR_START (0x1b8 = 440).
Later, omfs_make_empty() uses
sbi->s_sys_blocksize - OMFS_DIR_START
as the length argument to memset(). Since s_sys_blocksize is u32,
a crafted filesystem image with s_sys_blocksize < OMFS_DIR_START causes
an unsigned underflow there, wrapping to a value near 2^32. That drives
a ~4 GiB memset() from bh->b_data + OMFS_DIR_START and overwrites kernel
memory far beyond the backing block buffer.
Add the corresponding lower-bound check alongside the existing upper-bound
check in omfs_fill_super(), so that malformed images are rejected during
superblock validation before any filesystem data is processed.

The devpts_pts selftest has an ifdef in case an architecture does not
define TIOCGPTPEER, but the handling for this is broken since we need
errno to be set to EINVAL in order to skip the test as we should. Given
that this ioctl() has been defined since v4.15 we may as well just assume
it's there rather than write handling code which will probably never get

following process will access more than one buckets(which memory region
is not allocated) in dentry_hashtable:
d_lookup
b = d_hash(hash)
dentry_hashtable + ((u32)hashlen >> d_hash_shift)
// The C standard defines the behavior of right shift amounts
// exceeding the bit width of the operand as undefined. The
// result of '(u32)hashlen >> d_hash_shift' becomes 'hashlen',
// so 'b' will point to an unallocated memory region.
hlist_bl_for_each_entry_rcu(b)
hlist_bl_first_rcu(head)

Fix it by limiting the minimal number of dentry_hashtable bucket to two,
so that 'd_hash_shift' won't exceeds the bit width of type u32.

Pull more misc vfs updates from Christian Brauner:
"Features:
- Optimize close_range() from O(range size) to O(active FDs) by using
find_next_bit() on the open_fds bitmap instead of linearly scanning
the entire requested range. This is a significant improvement for
large-range close operations on sparse file descriptor tables.
- Add FS_XFLAG_VERITY file attribute for fs-verity files, retrievable
via FS_IOC_FSGETXATTR and file_getattr(). The flag is read-only.
Add tracepoints for fs-verity enable and verify operations,
replacing the previously removed debug printk's.
- Prevent nfsd from exporting special kernel filesystems like pidfs
and nsfs. These filesystems have custom ->open() and ->permission()
export methods that are designed for open_by_handle_at(2) only and
are incompatible with nfsd. Update the exportfs documentation
accordingly.
Fixes:
- Fix KMSAN uninit-value in ovl_fill_real() where strcmp() was used
on a non-null-terminated decrypted directory entry name from
fscrypt. This triggered on encrypted lower layers when the
decrypted name buffer contained uninitialized tail data.
The fix also adds VFS-level name_is_dot(), name_is_dotdot(), and
name_is_dot_dotdot() helpers, replacing various open-coded "." and
".." checks across the tree.
- Fix read-only fsflags not being reset together with xflags in
vfs_fileattr_set(). Currently harmless since no read-only xflags
overlap with flags, but this would cause inconsistencies for any
future shared read-only flag
- Return -EREMOTE instead of -ESRCH from PIDFD_GET_INFO when the
target process is in a different pid namespace. This lets userspace
distinguish "process exited" from "process in another namespace",
matching glibc's pidfd_getpid() behavior
Cleanups:
- Use C-string literals in the Rust seq_file bindings, replacing the
kernel::c_str!() macro (available since Rust 1.77)
- Fix typo in d_walk_ret enum comment, add porting notes for the
readlink_copy() calling convention change"

moved the context saving APIs around to fix a build error in certain
configurations. There was a change to the core framework for
CLK_OPS_PARENT_ENABLE behavior during registration, but it wrecked existing
drivers that didn't expect things to be turned off during clk registration so
it got reverted.
This cycle is really a large collection of new clk drivers, primarily for
Qualcomm SoCs but also for Amlogic, SpacemiT, Google, and Aspeed. Another big
change in here is support for automatic hardware clock gating on Samsung SoCs
where the clks turn on and off when needed. Ideally more vendors move to this
method for better power savings. The highlights are in the updates section
below.
Beyond all the new drivers we have a bunch of cleanups like converting drivers
from divider_round_rate() to divider_determine_rate() and using scoped for each
OF child loops. Otherwise it's the usual data fixes and plugging reference
leaks, etc. that's all pretty ordinary but not critical enough to fix until the
next release.
New Drivers:
- Qualcomm Kaanapali global, tcsr, rpmh, display, gpu, camera, and video clk
controllers
- Qualcomm SM8750 camera clk controllers
- Qualcomm MSM8940 and SDM439 global clk controllers
- Google GS101 Display Process Unit (DPU) clk controllers
- SpacemiT K3 clk controllers
- Amlogic t7 clk controllers
- Aspeed AST2700 clk controllers
Updates:
- Convert clock dividers from round_rate() to determine_rate()
- Fix sparse warnings, kernel-doc warnings, and plug leaked OF refs
- Automatic hardware clk gating on Google GS101 SoCs
- Amlogic s4 video clks
- CAN-FD clks and resets on Renesas RZ/T2H, RZ/N2H, RZ/V2H, and RZ/V2N
- Expanded Serial Peripheral Interface (xSPI) clocks and resets on Renesas
RZ/T21H and RZ/N2H
- DMAC, interrupt controller (ICU), SPI, and thermal (TSU) clocks and resets
on Renesas RZ/V2N
- More serial (RSCI) clocks and resets on Renesas RZ/V2H and RZ/V2N

In this development cycle, we focused on several key performance optimizations:
1) introducing large folio support to enhance read speeds for immutable files,
2) reducing checkpoint=enable latency by flushing only committed dirty pages,
and 3) implementing tracepoints to diagnose and resolve lock priority inversion.
Additionally, we introduced the packed_ssa feature to optimize the SSA footprint
when utilizing large block sizes.
Enhancement:
- support large folio for immutable non-compressed case
- support non-4KB block size without packed_ssa feature
- optimize f2fs_enable_checkpoint() to avoid long delay
- optimize f2fs_overwrite_io() for f2fs_iomap_begin
- optimize NAT block loading during checkpoint write
- add write latency stats for NAT and SIT blocks in f2fs_write_checkpoint
- pin files do not require sbi->writepages lock for ordering
- avoid f2fs_map_blocks() for consecutive holes in readpages
- flush plug periodically during GC to maximize readahead effect
- add tracepoints to catch lock overheads
- add several sysfs entries to tune internal lock priorities
Bug fix:
- fix lock priority inversion issue
- fix incomplete block usage in compact SSA summaries
- fix to show simulate_lock_timeout correctly
- fix to avoid mapping wrong physical block for swapfile
- fix IS_CHECKPOINTED flag inconsistency issue caused by concurrent atomic
commit and checkpoint writes
- fix to avoid UAF in f2fs_write_end_io()
