Add SCSI host and device info not elsewhere available to /proc/scsi/cciss/* Namely, connect cciss device instance with scsi host number, and give scsi host number, bus, target, lun, devicetype, and 8-byte cciss LUNID for each tapedrive/medium changer attached to a controller For instance: # cat /proc/scsi/cciss/2 cciss0: SCSI host: 2 c2b0t0l0 01 0x0000000000000001 Signed-off-by:

This patch adds support for "One Button Disaster Recovery" devices to the cciss driver. (OBDR devices are tape drives which can pretend to be cd-rom devices temporarily. Once booted the device can be reverted to a tape drive and data recovery operations can be automatically begun.) This is an enhancement request by a vendor/partner working on One Button Disaster Recovery. Signed-off-by:

The CCISS driver seems to loose track of DMA mappings created by it's fill_cmd() routine. Neither callers of this routine are extracting the DMA address created in order to do the unmap. Instead, they simply try to unmap 0x0. It's easy to see this problem on an x86_64 system when using the "swiotlb=force" boot option. In this case, the driver is leaking resources of the swiotlb and not causing a sync of the bounce buffer. Signed-off-by:

This patch changes the way we complete commands. In the old method when we got a completion we searched our command list from the top until we find it. This method uses a tag associated with each command (not SCSI command tagging) to index us directly to the completed command. This helps performance. Signed-off-by:

This patch removes a couple of functions dealing with configuration and replaces them with new functions. This implementation fixes some bugs associated with the ACUXE. It also allows a logical volume to be removed from the middle without deleting all volumes behind it. If a user has 5 logical volumes and decides he wants to reconfigure volume number 3, he can now do that without removing volumes 4 & 5 first. This code has been tested in our labs against all application software. Signed-off-by:

This patch adds a flag called busy_initializing. If there are multiple controllers in a server AND the HP agents are running it's possible the agents may try to poll a card that is still initializing if the driver is removed and then added again. Signed-off-by:

This patch adds new PCI and subsystem ID's that finally made the spec. It also include a name change for one controller. I know there's a lot of duplicat names but the fw folks wanted this for the different implementations. Even though the same ASIC is used it may be embedded on some platforms, standup card in others, and a mezzanine in other servers. Signed-off-by:

reiserfs should use mark_inode_dirty during reiserfs_file_write and reiserfs_commit_write. This makes sure the inode is properly flagged as dirty, which is used during O_SYNC to decide when to trigger log commits. This patch also removes the O_SYNC check from reiserfs_commit_write, since that gets dealt with properly at higher layers once we start using mark_inode_dirty. Thanks to Hifumi Hisashi <hifumi.hisashi@lab.ntt.co.jp> for catching this. Signed-off-by:

Andrew Morton authored
Explain the mysteries of set_current_state(). Quoth Linus: The scheduler itself never needs the memory barrier at all. The barrier is needed only if the user itself ends up testing some other thing afterwards, ie if you have set_process_state(TASK_INTERRUPTIBLE); if (still_need_to_sleep()) schedule(); then the "still_need_to_sleep()" thing may test flags and wakeup events, and then you _may_ want to (and often do) make sure that the write of TASK_INTERRUPTIBLE is serialized wrt the reads of any wakeup data (since the wakeup may have happened on another CPU). So the comment is somewhat wrong. We don't really _care_ whether the state propagates out to other CPU's since all of our actions are purely local, and there is nothing we do that is conditional on any other CPU: we're going to sleep unconditionally, and the scheduler only cares about _our_ state, not about somebody elses state.

Force a compiler error instead of a link error, because they are easier to track down. Idea stolen from code by Jan Beulich <jbeulich@novell.com> If the argument to BUILD_BUG_ON evaluates to non-zero the compiler will do: t.c:6: error: size of array `type name' is negative (surprised that gcc doesn't have an extension for this) Signed-off-by:

When open(O_CREAT) is called and the error, ENFILE, is returned, the file may be created anyway. This is counter intuitive, against the SUS V3 specification, and may cause applications to misbehave if they are not coded correctly to handle this semantic. The SUS V3 specification explicitly states "No files shall be created or modified if the function returns -1.". The error, ENFILE, is used to indicate the system wide open file table is full and no more file structs can be allocated. This is due to an ordering problem. The entry in the directory is created before the file struct is allocated. If the allocation for the file struct fails, then the system call must return an error, but the directory entry was already created and can not be safely removed. The solution to this situation is relatively easy. The file struct should be allocated before the directory entry is created. If the allocation fails, then the error can be returned directly. If the creation of the directory entry fails, then the file struct can be easily freed. Signed-off-by:

Discard *.exit.text sections on runtime. We cannot do this on link time because of the way BUG macros are implemented. If "__exit function" calls one of those macros, __bug_table section will reference this function. This is similar to ".altinstructions" situation on i386. *.exit.data seems to be OK in this respect and is discarded on link time. Signed-off-by:

It's a dword thing, and the value we write is a dword. Doing a byte write to it is nonsensical, and writes only the low byte, which only contains the enable bit. So we enable a nonsensical address (usually zero), which causes the controller no end of problems. Trivial fix, but nasty to find. Signed-off-by: -
