Subject: LU-15107 mdt: Exclusive create isn't replayed
X-Git-Tag: 2.14.56~66
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=da14903c4394cb476386c475ade5eda12b2a8aa7

LU-15107 mdt: Exclusive create isn't replayed

mdt_finish_open() fails on exclusive create check as
there isn't an infrormation that the file was created.

Set DISP_OPEN_CREATE for exclusive open replay,
as we know that the original request has succeeded.
