While looking at check_file_extent I thought that the code might be a bit cleaner than it actually is and cleaner as well. The first patch factors out the code dealing with inline extents into a separate function aptly named check_file_extent_inline. This allows to remove some inline-specific variable from check_file_extent. Patch 2 just moves the final check in the new function into the already existing branch handling the !compressed case. Finally the check which detects unknown extent types is moved first in check_file_extent, followed by the code to handle inline extents and finally the existing code to handle regular/prealloc extents is left intact.
This patchset brings no functional changes.
