The test is a copy of the part of the mount command that writes /etc/mtab.
So it's doing some sequence of link, write, flock. It does this thousands
of times, much of it in parallel. I'll get a trace of a single instance of
this so we can see what the actual syscalls are. I'll also see about
turning on the mutex debug. Give me a couple of hours.
If you want to look at the source code for the test, clone this:
git://oss.sgi.com/xfs/cmds/xfstests
and it's in src/t_mtab.c. It's driven by the "089" script.
