Luis Chamberlain	3d379b8d0d	fs/cachefiles: simplify one-level sysctl registration for cachefiles_sysctls ... There is no need to declare an extra tables to just create directory, this can be easily be done with a prefix path with register_sysctl(). Simplify this registration.

David Howells	a70f652626	cachefiles: Add some error injection support ... Add support for injecting ENOSPC or EIO errors. This needs to be enabled by CONFIG_CACHEFILES_ERROR_INJECTION=y. Once enabled, ENOSPC on things like write and mkdir can be triggered by: echo 1 >/proc/sys/cachefiles/error_injection and EIO can be triggered on most operations by: echo 2 >/proc/sys/cachefiles/error_injection Signed-off-by: David Howells <dhowells@redhat.com> Reviewed-by: Jeff Layton <jlayton@kernel.org> cc: linux-cachefs@redhat.com Link: https://lore.kernel.org/r/163819624706.215744.6911916249119962943.stgit@warthog.procyon.org.uk/ # v1 Link: https://lore.kernel.org/r/163906925343.143852.5465695512984025812.stgit@warthog.procyon.org.uk/ # v2 Link: https://lore.kernel.org/r/163967134412.1823006.7354285948280296595.stgit@warthog.procyon.org.uk/ # v3 Link: https://lore.kernel.org/r/164021532340.640689.18209494225772443698.stgit@warthog.procyon.org.uk/ # v4	2022-01-07 13:40:56 +00:00
