While trying to learn the Block Group code I've found some cleanup
possibilities for find_first_block_group().
Here's a proposal to make $ffbg a bit more easier to read by untangling the
gotos and if statements.
The patch set is based on misc-next from May 26 morning with
HEAD 3f4a266717ed ("btrfs: split btrfs_direct_IO to read and write part")
and xfstests showed no regressions to the base misc-next in my test setup.
Changes to v1:
- Pass btrfs_path instead of leaf & slot to read_bg_from_eb (Nikolay)
- Don't comment about the size change (Nikolay)
- Add Nikolay's Reviewed-by's
Johannes Thumshirn (3):
btrfs: remove pointless out label in find_first_block_group
btrfs: get mapping tree directly from fsinfo in find_first_block_group
btrfs: factor out reading of bg from find_frist_block_group
