Subject: xfstest generic/018 and ext4 defrag
I see an earlier thread about ext4 defrag problems causing this
failure on xfstest generic/018 running on ext4
generic/018 1s ... [failed, exit status 1] - output mismatch (see
/home/sfrench/xfstests/results//generic/018.out.bad)

but wasn't clear whether it was fixed upstream. It failed on two out
of three runs for me on most current ext4. My test is on most current
Ubuntu x86_64 (and with 3.18-rc3 kernel)
I couldn't find version info for e4defrag from the command line but
other ext4 tools are reasonably recent it seems as Ubuntu packages
them e.g. EXT2FS Library version 1.42.10, 18-May-2014
Is generic xfstest 18 still broken on ext4?
Also am curious about test generic/026
generic/026 [not run] ext4 does not define maximum ACL count
Is that expected?
