+Subject: [PATCH] Make vhba compatible with kernel 2.6.37 SCSI host API
+
+Due to the SCSI host lock push-down changes introduced in 2.6.37 (see
+http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=f281233d3eba15fb225d21ae2e228fd4553d824a
+for more details), trying to use current vhba on 2.6.37 leads to oopses
+and kernel panics - e.g. see http://bugs.gentoo.org/show_bug.cgi?id=350753
+
+Add some #ifdefs to enable compatibility both with 2.6.37 and older API.
+Note that if future kernel versions remove the DEF_SCSI_QCMD macro, this
+issue will need to be revisited.
