Subject: [SCSI] qla2xxx: Always serialize mailbox command execution.
X-Git-Tag: v2.6.29-rc3~8^2~9
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8eca3f39c4b11320787f7b216f63214aee8415a9;p=pandora-kernel.git

[SCSI] qla2xxx: Always serialize mailbox command execution.

Original code would incorrectly bypass serialization if the DPC
thread were performing a big-hammer operation (ISP abort).  This
short circuit, though rare, would subsequently stomp on a
secondary thread's mailbox command execution.  Found during
ISP81XX testing.
