[PATCH] xfstests: optionally run all tests under quota

[PATCH] xfstests: optionally run all tests under quota

[Eric Sandeen]

This patch might be a little heavy handed, but it seems to
work; if you set USE_QUOTA=1 in your environment, all
tests should be run with quota on and enabled.

This will hopefully help shake out some of the ext4
quota problems, although one needs to keep an eye
on the console to see whether warnings scroll by.

I'd rather prefer a -quota option to ./check than a magic
environment variable.

And here's the problem with committing 2 year old patches without
review:

$ grep "Can't initialize the DMAPI" [0-9]* | uniq
142.out.bad:Can't initialize the DMAPI
143.out.bad:Can't initialize the DMAPI
144.out.bad:Can't initialize the DMAPI
145.out.bad:Can't initialize the DMAPI
146.out.bad:Can't initialize the DMAPI
147.out.bad:Can't initialize the DMAPI
150.out.bad:Can't initialize the DMAPI
155.out.bad:Can't initialize the DMAPI
156.out.bad:Can't initialize the DMAPI

176.out.bad:Can't initialize the DMAPI
185.out.bad:Can't initialize the DMAPI

This breaks the dmapi mount error detection, and hence whether dmapi
is enabled or not in the kernel. The problem is this:

@@ -251,6 +277,7 @@ _scratch_mount_options()
 _scratch_mount()
 {
     _mount -t $FSTYP `_scratch_mount_options $*`
+    _setup_quota $SCRATCH_MNT
 }
 

means that callers no longer can check is the mount succeeded or not
by looking at the return of _scratch_mount(). Hence this code:

_dmapi_scratch_mount () {
    if [ `echo "$MOUNT_OPTIONS" | grep -c dmapi` -gt 0 -o \
        `echo "$MOUNT_OPTIONS" | grep -c dmi` -gt 0 ] ; then
        #already got dmapi options set
        _scratch_mount
        dmapi_mount_result=$?
    else
        _scratch_mount "-o dmapi,mtpt=$SCRATCH_MNT"
        dmapi_mount_result=$?
    fi

    if [ $dmapi_mount_result -ne 0 ] ; then
        _notrun "Assuming DMAPI modules are not loaded"
    fi
}

now fails to detect that mounts fail.

Can we revert this commit for now? If we really need this
functionality someone can fix the original patch and re-propose it...

Cheers,

Dave.
