Since commit c5ed63d66f24(tcp: fix three tcp sysctls tuning), sysctl_max_syn_backlog is determined by tcp_hashinfo->ehash_mask, and the minimal value is 128, and it will increase in proportion to the memory of machine.

2011-12-06lockdep, kmemcheck: Annotate ->lock in lockdep_init_map()Yong Zhang
Since commit f59de89 ("lockdep: Clear whole lockdep_map on initialization"), lockdep_init_map() will clear all the struct. But it will break lock_set_class()/lock_set_subclass(). A typical race condition is like below: CPU A CPU B lock_set_subclass(lockA); lock_set_class(lockA); lockdep_init_map(lockA); /* lockA->name is cleared */ memset(lockA); __lock_acquire(lockA); /* lockA->class_cache[] is cleared */ register_lock_class(lockA); look_up_lock_class(lockA); WARN_ON_ONCE(class->name != lock->name); lock->name = name; So restore to what we have done before commit f59de89 but annotate ->lock with kmemcheck_mark_initialized() to suppress the kmemcheck warning reported in commit f59de89.

2011-12-06xfs: fix nfs export of 64-bit inodes numbers on 32-bit kernelsChristoph Hellwig
The i_ino field in the VFS inode is of type unsigned long and thus can't hold the full 64-bit inode number on 32-bit kernels. We have the full inode number in the XFS inode, so use that one for nfs exports. Note that I've also switched the 32-bit file handles types to it, just to make the code more consistent and copy & paste errors less likely to happen.

2011-12-06ALSA: hda - Fix GPIO LED setup for IDT 92HD75 codecsTakashi Iwai
Some HP laptops with IDT 92HD75 codecs may use a GPIO > 4 for the mute LED, but currently the driver doesn't check this properly, and confuses the mute LED behavior. This ended up with the silent output on some HP laptops due to having another GPIO used as external amp control. This patch fixes the problem by checking the max GPIO count and comparing with the given value from DMI entry instead of magic fixed value 4 and 8, and adding a new field to indicate the VREF mute-LED behavior.

2011-12-06ASoC: Provide a more complete DMA driver stubMark Brown
Allow userspace applications to do more parameter setting by providing a more complete stub DMA driver specifying a wildcard set of formats and channels and essentially random values for the DMA parameters. This is required for useful runtime operation of the dummy DMA driver until we are able to figure out how to power up links and do hw_params() from DAPM. Sending to stable as without this the dummy driver is not terribly useful.

2011-12-06target/rd: fix or rewrite the copy routineSebastian Andrzej Siewior
So the code assumes that the sg list is only a array while in reality loopback SGL memory via scsi_cmnd into target-core may be already chained. This patch converts ramdisk code to use sg_miter logic from scatterlist.h in order to properly support passthrough SGL usage with transport_generic_map_mem_to_cmd() via loopback. With this patch the bug goes away. However after umount/mount of the device my files are gone. So something is still not right. After looking at it for a while I decided to rewrite the that part of the code and now things do work for me. For reference: - http://article.gmane.org/gmane.linux.scsi.target.devel/595 the sg_next() conversion - http://article.gmane.org/gmane.linux.scsi.target.devel/602 the rewrite of the copy code (nab: Fix compile warning in rd_MEMCPY) Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Cc: stable@kernel.org Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

It resets iscsi_cmd_t->data_length from se_cmd_t->data_length after transport_generic_allocate_tasks() has been invoked in iscsit_handle_scsi_cmd() RX context, and converts iscsi_cmd->residual_count usage to access iscsi_cmd->se_cmd.residual_count to get the proper residual count set by target-core.

2011-12-06target: Address legacy PYX_TRANSPORT_* return code breakageNicholas Bellinger
This patch removes legacy usage of PYX_TRANSPORT_* return codes in a number of locations and addresses cases where transport_generic_request_failure() was returning the incorrect sense upon CHECK_CONDITION status after the v3.1 converson to use errno return codes. This includes the conversion of transport_generic_request_failure() to process cmd->scsi_sense_reason and handle extra TCM_RESERVATION_CONFLICT before calling transport_send_check_condition_and_sense() to queue up response status. It also drops PYX_TRANSPORT_OUT_OF_MEMORY_RESOURCES legacy usgae, and returns TCM_LOGICAL_UNIT_COMMUNICATION_FAILURE w/ a response for these cases. transport_generic_allocate_tasks(), transport_generic_new_cmd(), backend SCF_SCSI_DATA_SG_IO_CDB ->do_task(), and emulated ->execute_task() have all been updated to set se_cmd->scsi_sense_reason and return errno codes universally upon failure. This includes cmd->scsi_sense_reason assignment in target_core_alua.c, target_core_pr.c and target_core_cdb.c emulation code. Finally it updates fabric modules to remove the legacy usage, and for TFO->new_cmd_map() callers forwards return values outside of fabric code. iscsi-target has also been updated to remove a handful of special cases related to the cleanup and signaling QUEUE_FULL handling w/ ft_write_pending() (v2: Drop extra SCF_SCSI_CDB_EXCEPTION check during failure from transport_generic_new_cmd, and re-add missing task->task_error_status assignment in transport_complete_task) Cc: Christoph Hellwig <hch@lst.de> Cc: stable@kernel.org Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
