these have been wrappers for the generic dma direction bits since 2.5.x. This patch converts the few remaining drivers and removes the macros. Arjan noticed there's some hunk in here that shouldn't. Updated patch below: Signed-off-by: -

Don't use cmd->request->nr_hw_segments as it may not be initialized (SG_IO in particular bypasses anything that initializes this and just uses scsi_do_req to insert a scsi_request directly on the head of the queue) and a bogus value here can trip up the checks to make sure that the number of segments will fit in the queue ring buffer, resulting in commands that are never completed. Fix up several issues with PCI DMA mapping and failure to check return values on the mappings. Make the check for space in the ring buffer happen after the DMA mapping is done since any checks done before the mapping has taken place are bogus. Doug Ledford <dledford@redhat.com>. Signed-off-by:

Remove internal lun discovery routines and support structures. Signed-off-by:

Add initial support for FC remote port infrastructure. o Use fc_remote_port...() registration and block/unlock functions. o Consolidate 'attribute' (fc-remote/sysfs) helpers into new qla_attr.c file. Signed-off-by: -
Remove internal command queuing from the driver. As is, this driver cannot tolerate cable-pulls as I/Os will begin to fail by the upper layers. o Should be used in conjuction with the 11-fc_rport_adds_2.diff patch. o Removes qla_listops.h file -- no longer needed. Signed-off-by: -

This patch makes scsi_send_eh_cmnd() use sdev and shost instead of referencing them through scmd-> everytime. Signed-off-by:

This patch removes volatile qualifier from scsi_device->device_busy, Scsi_Host->host_busy and ->host_failed as the volatile qualifiers don't serve any purpose now. While at it, convert those fields from unsigned short to unsigned int as suggested by Christoph. Signed-off-by:
-
We have a DID_IMM_RETRY to require a retry at once, but we could do with a DID_REQUEUE to instruct the mid-layer to treat this command in the same manner as QUEUE_FULL or BUSY (i.e. halt the submission until another command returns ... or the queue pressure builds if there are no outstanding commands).

Also broken design in its compat handlers - CONFIG_COMPAT doesn't mean that there should be no native ioctls. Signed-off-by:

Fix up two drivers that incorrectly were using the old return values for their new-style EH methods and kill off scsi_obsolete.h that defined the constants. The initio driver has all these constansts defined locally and uses them internally, I'll fix that up some time later. Signed-off-by: -
scsi_cmnd->serial_number_at_timeout doesn't serve any purpose anymore. All serial_number == serial_number_at_timeout tests are always true in abort callbacks. Kill the field. Also, as ->pid always equals ->serial_number and ->serial_number doesn't have any special meaning anymore, update comments above ->serial_number accordingly. Once we remove all uses of this field from all lldd's, this field should go. Signed-off-by:

scsi_cmnd->internal_timeout field doesn't have any meaning anymore. Kill the field. Signed-off-by:

- add a comment to the device structure that the device_busy field is now protected by the request_queue->queue_lock - null out sdev->request_queue after the queue is released to trap any (and there shouldn't be any) use after the queue is freed. Signed-off-by: -
The current problem seen is that the queue lock is actually in the SCSI device structure, so when that structure is freed on device release, we go boom if the queue tries to access the lock again. The fix here is to move the lock from the scsi_device to the queue. Signed-off-by: -
This driver has had it's own different infrastructure for doing this for ages, but it's time it used the common one. Signed-off-by: -

The attachment combines the most recent patch from Yum Rayan <yum.rayan@gmail.com> (to reduce sg stack usage), Adrian Bunk <bunk@stusta.de> (to fix check after use) and me (fix elapsed time calculation (duration) on ia64 machines). I have modified the patch from Yum Rayan so kmalloc() in sg_read() is only called for the (rare) code paths that need them. Changelog: - reduce stack usage in sg_ioctl() and sg_read() - fix check after use in sg_mmap() - hold duration internally in milliseconds and check current time later than held time Signed-off-by:Douglas Gilbert <dougg@torque.net> Signed-off-by:

The conditions that cause these calls to MD_BUG are not kernel bugs, just oddities in what userspace is asking for. Also convert analyze_sbs to return void, and the value it returned was always 0. Signed-off-by:

There is a tiny race when de-registering an MD thread, in that the thread could disappear before it is set a SIGKILL, causing send_sig to have problems. This is most easily closed by holding tasklist_lock between enabling the thread to exit (setting ->run to NULL) and telling it to exit. (akpm: ick. Needs to use kthread API and stop using signals) Signed-off-by:

Fix the formatting of some comments in 8250.c, and add a note that the register_serial / unregister_serial shouldn't be used in new code. We do this here in preference to adding to linux/serial.h, since that is used by a number of non-8250 drivers which pretend to be 8250. It is not known whether it would be appropriate to do so.

We were failing to close on an error path, resulting in a leak of struct files which could take a v4 server down fairly quickly.... So call nfs4_close_delegation instead of just open-coding parts of it. Simplify the cleanup on delegation failure while we're at it. Signed-off-by:

This fixes the lots-of-fsx-linux-instances-cause-a-slow-leak bug. It's been there since 2.6.6, caused by: ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.5/2.6.5-mm4/broken-out/jbd-move-locked-buffers.patch That patch moves under-writeout ordered-data buffers onto a separate journal list during commit. It took out the old code which was based on a single list. The old code (necessarily) had logic which would restart I/O against buffers which had been redirtied while they were on the committing transaction's t_sync_datalist list. The new code only writes buffers once, ignoring redirtyings by a later transaction, which is good. But over on the truncate side of things, in journal_unmap_buffer(), we're treating buffers on the t_locked_list as inviolable things which belong to the committing transaction, and we just leave them alone during concurrent truncate-vs-commit. The net effect is that when truncate tries to invalidate a page whose buffers are on t_locked_list and have been redirtied, journal_unmap_buffer() just leaves those buffers alone. truncate will remove the page from its mapping and we end up with an anonymous clean page with dirty buffers, which is an illegal state for a page. The JBD commit will not clean those buffers as they are removed from t_locked_list. The VM (try_to_free_buffers) cannot reclaim these pages. The patch teaches journal_unmap_buffer() about buffers which are on the committing transaction's t_locked_list. These buffers have been written and I/O has completed. We can take them off the transaction and undirty them within the context of journal_invalidatepage()->journal_unmap_buffer(). Acked-by:
