* Fix an integer overflow bug when processing an fsmap call.
* Fix crash due to CPU hot remove event racing with filesystem mount
operation.
* During read-only mount, XFS does not allow the contents of the log to be
recovered when there are one or more unrecognized rcompat features in the
primary superblock, since the log might have intent items which the kernel
does not know how to process.
* During recovery of log intent items, XFS now reserves log space sufficient
for one cycle of a permanent transaction to execute. Otherwise, this could
lead to livelocks due to non-availability of log space.
* On an fs which has an ondisk unlinked inode list, trying to delete a file
or allocating an O_TMPFILE file can cause the fs to the shutdown if the
first inode in the ondisk inode list is not present in the inode cache.
The bug is solved by explicitly loading the first inode in the ondisk
unlinked inode list into the inode cache if it is not already cached.
A similar problem arises when the uncached inode is present in the middle
of the ondisk unlinked inode list. This second bug is triggered when
executing operations like quotacheck and bulkstat. In this case, XFS now
reads in the entire ondisk unlinked inode list.
* Enable LARP mode only on recent v5 filesystems.
* Fix a out of bounds memory access in scrub.
* Fix a performance bug when locating the tail of the log during mounting a
filesystem.

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.
