Subject: [PATCH] selftests: ublk: fix build failure
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Fixes the following build failure:

ublk//file_backed.c: In function ‘backing_file_tgt_init’:
ublk//file_backed.c:28:42: error: ‘O_DIRECT’ undeclared (first use in this function); did you mean ‘O_DIRECTORY’?
   28 |                 fd = open(file, O_RDWR | O_DIRECT);
      |                                          ^~~~~~~~
      |                                          O_DIRECTORY

when trying to reuse this same utility for liburing test.
