From: Darrick J. Wong <djwong@xxxxxxxxxx> Repair only queries inode block maps for inode forks that map filesystem metadata. IOWs, it only uses it for directories, quota files, symlinks, and realtime space metadata. It doesn't use it for regular files or realtime files, so exclude its use for these files to reduce processing times for heavily fragmented regular files. Signed-off-by: Darrick J.
