Christian Brauner <brauner@kernel.org> says: I'm in the process of adding a few more guards for vfs constructs. I've chosen the easy case of super_start_write() and super_end_write() and converted eligible callers. I think long-term we can move a lot of the manual placement to completely rely on guards - where sensible. * patches from https://patch.msgid.link/20251104-work-guards-v1-0-5108ac78a171@kernel.org: xfs: use super write guard in xfs_file_ioctl() open: use super write guard in do_ftruncate() btrfs: use super write guard in relocating_repair_kthread() ext4: use super write guard in write_mmp_block() btrfs: use super write guard in sb_start_write() btrfs: use super write guard btrfs_run_defrag_inode() btrfs: use super write guard in btrfs_reclaim_bgs_work() fs: add super_write_guard Link: https://patch.msgid.link/20251104-work-guards-v1-0-5108ac78a171@kernel.org Signed-off-by: Christian Brauner <brauner@kernel.org>
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 reStructuredText 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.
