From 823564e4f3fc36a7c7fed4535541c57aa4552f13 Mon Sep 17 00:00:00 2001 From: Mark Harvey<markh794@xxxxxxxxx> Date: Fri, 27 Jan 2012 08:32:05 +1100 Subject: ssc: fsync on WRITE FILEMARK commit: 96e83a2e60857cd5356f99c45f0a0a658f600949 missed fsync() on zero filemarks count. SSC4r01e states: NOTE 43 - Upon completion of any buffered write operation, the application client may issue a WRITE FILEMARKS(6) command with the IMMED bit set to zero and the FILEMARK COUNT field set to zero to perform a synchronize operation The IMMED bit is defined as: a) written to the object buffer if the IMMED bit is set to one; or b) written to the medium if the IMMED bit is set to zero. This patch calls fsync() ignoring the IMMED bit value.
