Pull fscache fixes from David Howells: - Fix a check in fscache_wait_on_volume_collision() in which the polarity is reversed. It should complain if a volume is still marked acquisition-pending after 20s, but instead complains if the mark has been cleared (ie. the condition has cleared). Also switch an open-coded test of the ACQUIRE_PENDING volume flag to use the helper function for consistency. - Not a fix per se, but neaten the code by using a helper to check for the DROPPED state. - Fix cachefiles's support for erofs to only flush requests associated with a released control file, not all requests. - Fix a race between one process invalidating an object in the cache and another process trying to look it up. * tag 'fscache-fixes-20220708' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: fscache: Fix invalidation/lookup race cachefiles: narrow the scope of flushed requests when releasing fd fscache: Introduce fscache_cookie_is_dropped() fscache: Fix if condition in fscache_wait_on_volume_collision()
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.
