Looks good. I'm keeping the patch. It was placed through the
following tests:
*) the test suite from the January 19 git acl, as root;
(git://git.savannah.nongnu.org/acl.git)
*) the acl test suite, as a regular user;
*) xfstests (full run); and
*) some fs_mark and LTP fsstress in a dir populated with three
default ACLs.
Tests were done on an i686 Pentium 4 PC, using kernels 3.14.0-rc1+
and 3.13.0+. Comparisons were made with standard XFS. Due to non-JFS
issues, lockdep is off and CONFIG_AIO=n, meaning that their effects
are not represented here.
The xfstests run for JFS looked unchanged over kernel 3.13.0+, with
the exeption of the error "+error: ctime not updated after setfacl"
from generic/307. The test uses integer seconds to compare ctime, so
I inserted some regular stat commands into the test. The nanosecond
portion of the timestamps also do not change. JFS from 3.13.0+
passed this test; XFS from 3.14.0-rc1+ passed this test as well.
For JFS, the new generic ACL infrastructure provides a reduction of
99 failures from the acl test suite, most of them from the misc.test
series of tests. Pass or fail, results were equal to that of XFS,
which seemed to gain 10 errors from the root/*.test tests.
Thanks! Christoph's generic ACL work now makes much more sense to
me than it did at this time yesterday. The prompt patch from Shaggy
allows me to use it on JFS as well :-)

I missed a couple errors in reviewing the patches converting jfs
to use the generic posix ACL function. Setting ACL's currently
fails with -EOPNOTSUPP.
