There are two comments in btrfs_cache_block_group that I left when resolving conflict between commitsced8ecf026"btrfs: fix space cache corruption and potential double allocations" and527c490f44"btrfs: delete btrfs_wait_space_cache_v1_finished". The former reworked the caching logic to wait until the caching ends in btrfs_cache_block_group while the latter only open coded the waiting. Both removed btrfs_wait_space_cache_v1_finished, the correct code is with the waiting and returning error. Thus the conflict resolution was OK. Signed-off-by: David Sterba <dsterba@suse.com>
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.
