Subject: [GIT PATCH] SCSI bug fixes for 2.6.31-rc1
Surprisingly we only have a small number of these, and they're spread
around both the new features and the old code (the fix checks on
unsigned actually prevents an oops on dma mapping failure). The patch
is here:
master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-rc-fixes-2.6.git
The short changelog is:
fnic: use DMA_BIT_MASK(nn) instead of deprecated DMA_nnBIT_MASK
Brian King (1):
ibmvscsi: Fix module load hang
Christof Schmitt (1):
FC transport: Locking fix for common-code FC pass-through patch
James Bottomley (1):
zalon: fix oops on attach failure
Karen Xie (1):
cxgb3i: fix connection error when vlan is enabled
Roel Kluin (1):
fnic: remove redundant BUG_ONs and fix checks on unsigned
