From: Omar Sandoval <osandov@xxxxxx> Currently, we always reserve the same extent size in the file and extent size on disk for delalloc because the former is the worst case for the latter. For RWF_ENCODED writes, we know the exact size of the extent on disk, which may be less than or greater than (for bookends) the size in the file. Add a disk_num_bytes parameter to btrfs_delalloc_reserve_metadata() so that we can reserve the correct amount of csum bytes. No functional change.
