2.6.21-rc5-mm2 VFS panics unable to find my root on /dev/sda2, but boots
okay if I change drivers/scsi/Kconfig to "default y" instead of "default m"
for SCSI_WAIT_SCAN.
Make sure there's a late_initcall to scsi_complete_async_scans when it's
built in, so a monolithic SCSI_SCAN_ASYNC kernel can rely on the scans
being completed before trying to mount root, even if they're slow.

Every so often, the driver will call asd_clear_nexus to clean out a task.
It is supposed to be the case that the CLEAR NEXUS does not go on the done
list until after the task itself has been put on the done list, but for
some reason this doesn't always happen. Thus, the
wait_for_completion_timeout call times out, and we return success. This
makes libsas free the task even though the task hasn't completed, leading
to a BUG_ON message from aic94xx_hwi.c around line 341. We should return
failure from asd_clear_nexus so that libsas tries again; at a bare minimum
it shouldn't be freeing active tasks. I _think_ this will fix one of
the SCB timeout crash problems (though I've not been able to reproduce
it lately...)

Under some conditions associated with the unclean transition to kdump,
the aacraid adapters will view the array as foreign and not export it to
prevent access and data manipulation. The solution is to submit a commit
configuration to export the devices since this is a expected behavior
when transitioning to a kdump kernel.
This patch adds the aacraid.reset_devices flag and when either this or
the global reset_devices flag is set, ensures that a commit config is
issued and extends the startup_timeout if it is set less than 5 minutes.

Back in the beginning of last year we disabled mode page 8 and mode page
3f requests through device quirk bits instead of enhancing the driver to
respond to these mode pages because there was no apparent added value.
The Firmware that supports the new communication commands supports the
ability to force a write around of the adapter cache on a command by
command basis. In the attached patch we enable mode page 8 and 3f and
spoof the results as needed in order to *convince* the layers above to
submit writes with the FUA (Force Unit Attention) bit set if the file
system or application requires it, if the Firmware supports the write
through, or instead to submit a SYNCHRONIZE_CACHE if the Firmware does
not. The added value here is for file systems that benefit from this
functionality and for clustering or redundancy scenarios.
Caveats: By convince, we are responding with a minimal short 3 byte
content mode page 8, with only the data the SCSI layer needs and that we
can fill confidently. Applications that require the customarily larger
mode page 8 results may be confused by this(?). The FUA, or the
SYNCHRONIZE_CACHE only affect the cache on the controller. Our firmware
by default ensure that the underlying physical drives of the array have
their cache turned off so normally this is not a problem.
This attached patch is against current scsi-misc-2.6 and was unit tested
on RHEL5. Since this is a feature enhancement, it should not be
considered for any current stabilization efforts.

First thing mm.h does is including sched.h solely for can_do_mlock() inline
function which has "current" dereference inside. By dealing with can_do_mlock()
mm.h can be detached from sched.h which is good. See below, why.
This patch
a) removes unconditional inclusion of sched.h from mm.h
b) makes can_do_mlock() normal function in mm/mlock.c
c) exports can_do_mlock() to not break compilation
d) adds sched.h inclusions back to files that were getting it indirectly.
e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
getting them indirectly
Net result is:
a) mm.h users would get less code to open, read, preprocess, parse, ... if
they don't need sched.h
b) sched.h stops being dependency for significant number of files:
on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
after patch it's only 3744 (-8.3%).

controllers are HP NetRAID, Adaptec AAC-364, Dell PERC2/QC or Adaptec

After reset completed, the scsi error handler sends out TEST_UNIT_READY

However, because the RAID console only interfaces to scsi mid layer, the
firmware will not process the command for it. This will make the console to

The correct internal mapping of stex controllers should be:

id:0~127, lun:0 (st_vsc and st_vsc1)
This patch reports the internal mapping to scsi mid layer, eliminating
the translation between scsi mid layer and firmware. To achieve this
goal, we also need to:
-- fail the REPORT_LUNS command for st_shasta because the
firmware is known to not report all actual luns
-- add an entry in scsi_devindo.c to force sequential lun scan
(for st_shasta controllers)
-- fail the REPORT_LUNS command for console device
-- remove special handling of REPORT_LUNS command for

The RFC was originally posted here:
http://marc.info/?l=linux-scsi&m=117226959918393&w=2
Changes from the initial RFC:
- Bug fix: needed a transport_class_unregister() for the vport class
- Create a symlink to the vport in the shost device if it is not the
parent of the vport.
- Made symbolic name writable so it can be set after creation
- Made the temporary fc_vport_identifiers struct private to the
transport.
- Deleted the vport_id field from the vport. I couldn't find any good
use for it (and symname is a good replacement).
- Made the vport_state and vport_last_state "private" attributes.
Added the fc_vport_set_state() helper function to manage state
transitions
- Updated vport_create() to allow a vport to be created in a disabled
state.
- Added INITIALIZING and FAILED vport states
- Added VPCERR_xxx defines for errors to be returned from vport_create()

Use a newly added PCI API to issue a PCI Fundamental reset
(warm reset) to a new ipr PCI-E adapter. Typically, the
ipr adapter uses the start BIST bit in config space to reset
an adapter. Issuing start BIST on this particular adapter
results in the PCI-E logic on the card losing sync, which
causes PCI-E errors, making the card unusable. The only reset
mechanism that exists on this hardware that does not have this

Per the comment in the change - it's not always prudent to immediately
remove the rport upon first notice of a disconnect. Make all rports
wait dev_loss_tmo before being deleted (and each could have a separate
dev_loss_tmo value).
The original post was:
http://marc.info/?l=linux-scsi&m=117392196006703&w=2
The repost contains the following changes:
- Bug fix in fc_starget_delete(). Dev_loss_tmo_callbk() was called prior to
tearing down the target. The callback is to be the last thing called, as
it tells the LLDD that the rport is completely finished and can be torn
down. Rework so that terminate_rport_io() is called to terminate the
outstanding io. Isolated work so it's is simply "starget" work.
- Fix holes in original patch. There were code paths that did not expect
the dev_loss_tmo timer to be running for the non-fcp rports.
- Bug Fix: the transport wasn't protecting against a LLDD calling
fc_remote_port_delete() back-to-back. Thus, the dev_loss_tmo timer
could be restarted such that it fires after the rport had been deleted.
Validate rport state before starting the timer.

This patch fixes some scenarios where an ipr adapter
could get reset overlapped, which could cause very
long timeouts to occur, or PCI bus errors.

Add support for async scanning
Notes: This is the async scan patch to our driver from Matthew Wilcox.
The async scan logic is still subject to errors in insmod/rmmod, as
the async scan threads don't get shutdown when the module unloads
underneath them. See http://marc.info/?l=linux-scsi&m=117551999925582&w=2
