looks like we better do something urgently to fix this.
Any suggestions Christoph?

Subject: [xfs-masters] [Bug 11813] New: xfs filesystem exported via nfs
don't work in 126.96.36.199
Date: Thu, 23 Oct 2008 12:32:51 -0700 (PDT)
Summary: xfs filesystem exported via nfs don't work in 188.8.131.52
Product: File System
Latest working kernel version: 184.108.40.206
Earliest failing kernel version: 220.127.116.11
With kernel 18.104.22.168, it's impossible to use a xfs filesystem exported via
NFS. I am using gentoo and I share a portage tree mounted on an xfs
via NFS. Each time packages are fetched, the emerge process is blocked. It
seems the problematic commit is the following:

xfs: fix remount rw with unrecognized options
commit 6c5e51dae2c37127e00be392f40842e08077e96a upstream
When we skip unrecognized options in xfs_fs_remount we should just
out of the switch and not return because otherwise we may skip clearing
the xfs-internal read-only flag. This will only show up on some
operations like touch because most read-only checks are done by the VFS
which thinks this filesystem is r/w. Eventually we should replace the
XFS read-only flag with a helper that always checks the VFS flag to
sure they can never get out of sync.
Bug reported and fix verified by Marcel Beister on #xfs.
Bug fix verified by updated xfstests/189.
If I revert it, the problem doesn't occur.
