Subject: xfs_repair: adjust keep_fsinos to handle metadata directories
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=3c340f66fa2bc6118d16106012315b327b9001da;p=users%2Fhch%2Fxfsprogs.git

xfs_repair: adjust keep_fsinos to handle metadata directories

On a filesystem with metadata directories, we only want to automatically
mark the two root directories present because those are the only two
statically allocated inode numbers -- the rt summary inode is now just a
regular file in a directory.
