Subject: [PATCH] df: improve mount point selection with inaccurate mount list
|
|
|
|
v8.23 has a test failure on Fedora rawhide build servers
|
|
in tests/df/skip-duplicate.sh. This was due to no '/'
|
|
entry being output by df. That was due to an inaccurate
|
|
/proc/mounts on the build environment as stat(/mnt/point)
|
|
identified all these /proc/mounts entries as having the
|
|
same device id:
|
|
|
|
/ rootfs
|
|
/ /dev/md1
|
|
/dev devtmpfs
|
|
/run tmpfs
|
|
/boot /dev/md0
|
|
/proc/filesystems /dev/md1
|
|
|
|
Since the device name on the right changes for a given id,
|
|
that causes the entries to be continually replaced, thus
|
|
resulting in no '/' entry. I'm guessing this is due to
|
|
the mock environment bind mounting unneeded or sensitive
|
|
items to a dummy file on the host / (/dev/md1) though
|
|
have not looked into those details.
|
|
|
|
So rather than relying on an accurate /proc/mounts,
|
|
the attached patch takes a more conservative replacement
|
|
approach and only swaps a new device entry when the
|
|
mount point matches. That should handle all practical
|
|
cases while also avoiding this situation.
|
|
|
|
* src/df.c (filter_mount_list): Only replace entries with
|
|
different device names when the mount point also matches.
