When subvolumes & snapshots were rolled out, hash_redo_key() was disabled due to some new complications - namely, bch2_hash_set() works at the subvolume level, and fsck does not run in a defined subvolume, instead working at the snapshot ID level. This patch splits out bch2_hash_set_snapshot() from bch2_hash_set(), and makes one small tweak for fsck: - Normally, bch2_hash_set() (and other dirent code) needs to know what subvolume we're in, because dirents that point to other subvolumes should only be visible in the subvolume they were created in, not other snapshots. We can't check that in fsck, so we just assume that all dirents are visible. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
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.
