Patch series "Fix invalid wait context of set_track_prepare()". Geert reported an invalid wait context[1] which is resulted by moving set_track_prepare() inside kmemleak_lock. This is not allowed because in RT mode, the spinlocks can be preempted but raw_spinlocks can not, so it is not allowd to acquire spinlocks while holding raw_spinlocks. The second patch fix same problem in kmemleak_update_trace(). This patch (of 2): Move the initialisation of object back to__alloc_object() because set_track_prepare() attempt to acquire zone->lock(spinlocks) while __link_object is holding kmemleak_lock(raw_spinlocks). This is not right for RT mode. This reverts commit |

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
