Re: More tests added to buildbot

[Steve French <smfrench@gmail.com>]

I tried it to Samba a few minutes ago and it worked fine with current for-next
 and also:q it looks important (data integrity etc.).  Test description

# Test that mmap read doesn't see non-zero data past EOF on truncate down.
#
# This is inspired by an XFS bug that truncate down fails to zero page cache
# beyond new EOF and causes stale data written to disk unexpectedly and a
# subsequent mmap reads and sees non-zeros post EOF.

I have two test targets, both Samba localhost.  One succeeds for all 8 of
the ones that we were worried about:

./check -cifs generic/013 generic/014 generic/024 generic/030
generic/069 generic/075 generic/112 generic/125 generic/346
generic/469

The other succeeds on all but 075 and 112 which worked on the 'old'
xfstests from a month ago, but fail on the one with the newer
xfstests.

So I think we are ok with 469 ... but we do have to figure out what to
do with what seems to be either a regression in 075 and 112 xfstests
(a bug in the tests) or something that the updated tests are now
seeing as a cifs bug.  My theory is that it is due to this xfstest

    generic/075,112: detect preallocation support for fsx tests

    Currently generic/075 and generic/112 have two extra fsx passes each
    that exercise fsx with preallocation, which are only enabled for
    XFS.

    These tests can also be run with other file systems, given that the
    XFS prealloc ioctls are implemented in generic code since the
    addition of the fallocate system call.  This also means a version of
    XFS that does not support preallocation (e.g. because it always
    writes out of place) can skip the prealloc tests while still
    completing the normal fsx tests just fine.
