Hi Fengguang,
feel free to try this git tree:
git://git.infradead.org/users/hch/vfs.git iomap-fixes
I just queued some test jobs for it.

That job file can be found here:
https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/tree/jobs/aim7-fs-1brd.yaml
It specifies a matrix of the below atom tests:

I got some results now. The several finished aim7 tests have some
performance regressions for commit fe9c2c81 ("xfs: rewrite and
optimize the delalloc write path") comparing to its parent commit
ca2edab2e and their base mainline commit 990917006 ("Merge tag
'nfs-for-4.8-2' of git://git.linux-nfs.org/projects/trondmy/linux-nfs").

Here are the detailed numbers for each test case. The perf-profile and
latency_stats numbers are sorted by absolute change in each sub-category
now. perf-profile numbers > 5 are all shown.
It may be more pleasant to view the long trace.call.funcs lines with
vim ":set nowrap" option.
