Be a bit more careful about when bch2_delete_dead_snapshots needs to run: it only needs to run synchronously if we're running fsck, and it only needs to run at all if we have snapshot nodes to delete or if fsck has noticed that it needs to run. Also: Rename BCH_FS_HAVE_DELETED_SNAPSHOTS -> BCH_FS_NEED_DELETE_DEAD_SNAPSHOTS Kill bch2_delete_dead_snapshots_hook(), move functionality to bch2_mark_snapshot() Factor out bch2_check_snapshot_needs_deletion(), to explicitly check if we need to be running snapshot deletion.

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.
