+Subject: [PATCH] xfsprogs: ignore autofs mount table entries
+
+Some of the xfsprogs utilities read the mount table via. getmntent(3).
+
+The mount table may contain (almost always these days since /etc/mtab is
+symlinked to /proc/self/mounts) autofs mount entries. During processing
+of the mount table entries statfs(2) can be called on mount point paths
+which will trigger an automount if those entries are direct or offset
+autofs mount triggers (indirect autofs mounts aren't affected).
+
+This can be a problem when there are a lot of autofs direct or offset
+mounts because real mounts will be triggered when statfs(2) is called.
+This can be particularly bad if the triggered mounts are NFS mounts and
+the server is unavailable leading to lengthy boot times or worse.
+
+Simply ignoring autofs mount entries during getmentent(3) traversals
+avoids the statfs() call that triggers these mounts. If there are
+automounted mounts (real mounts) at the time of reading the mount table
+these will still be seen in the list so they will be included if that
+actually matters to the reader.
+
+Recent glibc getmntent(3) can ignore autofs mounts but that requires the
+autofs user to configure autofs to use the "ignore" pseudo mount option
+for autofs mounts. But this isn't yet the autofs default (to prevent
+unexpected side effects) so that can't be used.
+
+The autofs direct and offset automount triggers are pseudo file system
+mounts and are more or less useless in terms on file system information
+so excluding them doesn't sacrifice useful file system information
+either.
+
+Consequently excluding autofs mounts shouldn't have any adverse side
+effects.
+
+Changes since v1:
+- drop hunk from fsr/xfs_fsr.c.
