btrfs: use aligned range for locking in extent_fiemap()

Browse source

The @end parameter for all extent io tree helpers is inclusive, but
the call site in extent_fiemap() is passing an exclusive end into
btrfs_lock_extent(), which will step into the next block unexpectedly.

Pass the inclusive end into btrfs_lock_extent() and
btrfs_unlock_extent().
