[SCSI] zfcp: Add zfcp private struct as SCSI device driver data

Add a new data structure zfcp_scsi_dev that holds zfcp private data
for each SCSI device. Use scsi_transport_reserve_device to let the
SCSI midlayer automatically allocate this with each SCSI device.

This patch updates the scsi_debug virtual LLD to use

include/linux/device.h instead of device_register() and
device_unregister() respectively within scsi_debug_init() and

When an rport is "blocked" and a bsg request is received, the bsg request gets

After discussions about if the value should be configurable and

cache timeout to 1 minute. 2 minutes was determined to be too long, and
making it configurable was troublesome for users.

This patch was made over Linus's tree. It is not made over scsi-misc

firewire: ohci: work around VIA and NEC PHY packet reception bug

VIA VT6306, VIA VT6308, and NEC OrangeLink controllers do not write
packet event codes for received PHY packets (or perhaps write
evt_no_status, hard to tell).  Work around it by overwriting the
packet's ACK by ack_complete, so that upper layers that listen to PHY
packet reception get to see these packets.

(Also tested:  TI TSB82AA2, TI TSB43AB22/A, TI XIO2213A, Agere FW643,
JMicron JMB381 --- these do not exhibit this bug.)

Clemens proposed a quirks flag for that, IOW whitelist known misbehaving
controllers for this workaround.  Though to me it seems harmless enough
to enable for all controllers.

The log_ar_at_event() debug log will continue to show the original
status from the DMA unit.

Hugh Dickins [Thu, 26 Aug 2010 06:12:54 +0000]
mm: fix hang on anon_vma->root->lock

After several hours, kbuild tests hang with anon_vma_prepare() spinning on
a newly allocated anon_vma's lock - on a box with CONFIG_TREE_PREEMPT_RCU=y
(which makes this very much more likely, but it could happen without).

The ever-subtle page_lock_anon_vma() now needs a further twist: since
anon_vma_prepare() and anon_vma_fork() are liable to change the ->root
of a reused anon_vma structure at any moment, page_lock_anon_vma()
needs to check page_mapped() again before succeeding, otherwise
page_unlock_anon_vma() might address a different root->lock.

Julia Lawall [Sat, 28 Aug 2010 02:31:56 +0000]
net/ipv4: Eliminate kstrdup memory leak

The string clone is only used as a temporary copy of the argument val
within the while loop, and so it should be freed before leaving the
function.  The call to strsep, however, modifies clone, so a pointer to the
front of the string is kept in saved_clone, to make it possible to free it.

The sematic match that finds this problem is as follows:

Marks were stored on the inode and vfsmonut mark list in order from

When file name encryption was enabled, ecryptfs_lookup() failed to use
the encrypted and encoded version of the upper, plaintext, file name
when performing a lookup in the lower file system. This made it
impossible to lookup existing encrypted file names and any newly created
