* [SCSI] libsas: Add a sysfs knob to enable/disable a phyDarrick J. Wong2007-01-135-2/+90
| | | | | | | | | | This patch lets a user arbitrarily enable or disable a phy via sysfs. Potential applications include shutting down a phy to replace one lane of wide port, and (more importantly) providing a method for the libata SATL to control the phy. Signed-off-by: Darrick J.

* [SCSI] libsas: Don't give scsi_cmnds to the EH if they never made it to the ↵Darrick J. Wong2007-01-133-0/+17
| | | | | | | | | | | | | | | | | | | | | SAS LLDD or have already returned On a system with many SAS targets, it appears possible that a scsi_cmnd can time out without ever making it to the SAS LLDD or at the same time that a completion is occurring. In both of these cases, telling the LLDD to abort the sas_task makes no sense because the LLDD won't know about the sas_task; what we really want to do is to increase the timer. Note that this involves creating another sas_task bit to indicate whether or not the task has been sent to the LLDD; I could have implemented this by slightly redefining SAS_TASK_STATE_PENDING, but this way seems cleaner. This second version amends the aic94xx portion to set the TASK_AT_INITIATOR flag for all sas_tasks that were passed to lldd_execute_task. Signed-off-by: Darrick J.

* [SCSI] libsas: Clean up rphys/port dev list after a discovery error on an ↵Darrick J. Wong2007-01-131-4/+16
| | | | | | | | | | | | | | | | | expander sas_get_port_device assigns a rphy to a domain device in anticipation of finding a disk. When a discovery error occurs in sas_discover_{sata,sas,expander}*, however, we need to clean up that rphy and the port device list so that we don't GPF. In addition, we need to check the result of the second sas_notify_lldd_dev_found. This patch seems ok on a x260, x366 and x206m. This patch fixes up sas_expander.c separately because jejb has some cleanup patches of his own that are a prerequisite. Signed-off-by: Darrick J.

* [SCSI] scsi_scan message cosmetic errorKurt Garloff2007-01-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Hi, Minor typo ... In my first iteration of patches (that got merged), the BLIST_ATTACH_PQ3 actually had the value 0x800000, but that got changed later to avoid conflicts. This piece must have been overlooked. You could obviously do something like %x and then add the bitflags, but that looks overkill for something that does not tend to change. Please merge. (Patch applied against latest 2.6.20rc version that I tested.)

| | | | | | | | | | | | | | | | | | | | | | After discussions in the thread titled: [PATCH] scsi_debug: illegal blocking memory allocation here is a patch containing the discussed fix and some other fixes and additions. The patch is against lk 2.6.20-rc3 . The version is bumped to 1.81 . ChangeLog: - Change several GFP_KERNEL allocations to GFP_ATOMIC as they can be called from queuecommand() context - check above allocation returns and if out of memory report DID_REQUEUE in two cases, DID_NO_CONNECT in another, and fail slave configure() in another - add support for WRITE BUFFER command - add aborted_command error injection support (opts mask 0x10), similar mechanism to recovered_error injection.

Only after the call to unmap_mapping_range() are we sure that the page can no longer be dirtied. In order to fix this, NFS has hooked the releasepage() method and tries to write the page out between the call to unmap_mapping_range() and the call to remove_mapping(). This, however leads to deadlocks in the page reclaim code, where the page may be locked without holding a reference to the inode or dentry. Fix is to add a new address_space_operation, launder_page(), which will attempt to write out a dirty page without releasing the page lock.

Fixing this in raid1 and raid10 seems to be straightforward enough. For our particular usage case in DRBD, passing this flag improved some initialization time from ~5 minutes to ~5 seconds.

Since __cpuinit would map to __init with this kind of a configuration, we get a .text refering .init.data warning. This patch solves the problem by converting all of __cpu_up, _cpu_up and cpu_up from __devinit to __cpuinit. The approach is justified since the callers of cpu_up are either dependent on CONFIG_HOTPLUG_CPU or are of __init type. Thus when CONFIG_HOTPLUG_CPU=y, all these cpu up functions would land up in .text section, and when CONFIG_HOTPLUG_CPU=n, all these functions would land up in .init section.
