[PATCH 0/4] Misc cleanups of btrfs_get_extent

[Nikolay Borisov <nborisov@suse.com>]

Here is a series that hopefully makes the code a bit more obvious. First patch 
gives a variable a more appropraite name, since it's going to be used only for 
holding an extent type and not the type of a found item. 

Patch 2 simply consolidated separate 'if' statements that check the retval of
the same function into a single 'if() {} else if () {}' statement. IMO this is 
cleaner.

Patch 3 massages the abhorrent code that deals with btrfs_lookup_file_extent
retval. It groups everything in a coherent 'if() {} else if () {} else {}' 
construct and now it's obvious under what conditions specific code is executed. 

Finally, Patch 4 removes the not_found_em labelin the same function.

Nikolay Borisov (4):
  btrfs: Rename found_type to extent_type
  btrfs: Consolidate retval checking of core btree functions
  btrfs: Refactor retval handling of btrfs_lookup_file_extent in
    btrfs_get_extent
  btrfs: Remove not_found_em label from btrfs_get_extent
