xfs: various fixes for 6.2 This is an assorted collection of bug fixes that have been bundled together. The first patch fixes a metadump corruption vector resulting from a three-way race between a slow-running blkid process, the kernel mounting, changing, and unmounting the fs, and xfs_db reading stale block device pagecache contents. The middle two patches address gcc warnings. The final patch fixes a subtle corruption bug wherein making a delalloc reservation on a filesystem with quotas enabled would sample the data mapping, try to attach dquots, unlock the inode to attach the dquots, relock the inode, and fail to reverify the sampled data. If another process updated the data mapping while the inode was unlocked, the reservation would proceed with stale data and corrupt the data fork. Signed-off-by: Darrick J.

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.
