[0/3] Tree and inode lookup cleanups

Message

David Sterba May 15, 2020, 5:35 p.m. UTC

Simplify functions that take struct key for lookup but don't use all the
members. Reduces size of .ko by about 1.2K and stack consumption is
reduced by 450 bytes in total.

David Sterba (3):
  btrfs: simplify root lookup by id
  btrfs: open code read_fs_root
  btrfs: simplify iget helpers
