2005-08-14Revert "dc395x: Fix support for highmem"Linus Torvalds
It introduces a repeatable oops in the driver, which is a bigger problem than the patch tries to solve.

2005-08-10[PATCH] sata: fix sata_sx4 dma_prep to not use sg->lengthTejun Heo
sata_sx4 directly references sg->length to calculate total_len in pdc20621_dma_prep(). This is incorrect as dma_map_sg() could have merged multiple sg's into one and, in such case, sg->length doesn't reflect true size of the entry. This patch makes it use sg_dma_len(sg).

2005-08-08[SCSI] fix target scanning oops with fc transport classJames.Smart@Emulex.Com
We have some nasty issues with 2.6.12-rc6. Any request to scan on the lpfc or qla2xxx FC adapters will oops. What is happening is the system is defaulting to non-transport registered targets, which inherit the parent of the scan. On this second scan, performed by the attribute, the parent becomes the shost instead of the rport. The slave functions in the 2 FC adapters use starget_to_rport() routines, which incorrectly map the shost as an rport pointer. Additionally, this pointed out other weaknesses: - If the target structure is torn down outside of the transport, we have no method for it to be regenerated at the proper parent. - We have race conditions on the target being allocated by both the midlayer scan (parent=shost) and by the fc transport (parent=rport).

2005-08-04[SCSI] fix aic7xxx performance issues since 2.6.12-rc2James Bottomley
Several people noticed we dropped quite a bit on benchmark figures. OK, it was my fault but unfortunately I discovered I ran out of brown paper bags a while ago and forgot to reorder them. The issue is that a construct introduced in the conversion of the driver to use the transport class keyed off whether the block request was tagged or not. However, the aic7xxx driver doesn't properly set up the block layer TCQ (it uses the wrong API), so the driver now things all requests are untagged and we keep it to a queue depth of a single element. Oops. The fix is to use the correct TCQ API. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2005-08-02[SCSI] Fix SCSI tape oops at module removalKai Makisara
Removing the SCSI tape module results in an oops in class_device_destroy if any devices are present. The patch at the end of this message fixes the bug by moving class_destroy() later in exit_st() so that the class still exists when devices are removed. (The bug is old but class_simple_device_remove() did nothing when the class did not exist.) The patch also fixes a "class leak" in init_st() error path.

2005-07-31[PATCH] SCSI_SATA has to be a tristateAdrian Bunk
SCSI=m must disallow static drivers. The problem is that all the SATA drivers depend on SCSI_SATA. With SCSI=m and SCSI_SATA=y this allows the static enabling of the SATA drivers with unwanted effects, e.g.: - SCSI=m, SCSI_SATA=y, SCSI_ATA_ADMA=y -> SCSI_ATA_ADMA is built statically but scsi/built-in.o is not linked into the kernel - SCSI=m, SCSI_SATA=y, SCSI_ATA_ADMA=y, SCSI_SATA_AHCI=m -> SCSI_ATA_ADMA and libata are built statically but scsi/built-in.o is not linked into the kernel, SCSI_SATA_AHCI is built modular (unresolved symbols due to missing libata) Signed-off-by: Adrian Bunk <bunk@stusta.de> Cc: Jeff Garzik <jgarzik@pobox.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2005-07-14[SCSI] add int_to_scsilun() functionJames.Smart@Emulex.Com
One of the issues we had was reverting the midlayers lun value into the 8byte lun value that we wanted to send to the device. Historically, there's been some combination of byte swapping, setting high/low, etc. There's also been no common thread between how our driver did it and others. I also got very confused as to why byteswap routines were being used. Anyway, this patch is a LLDD-callable function that reverts the midlayer's lun value, stored in an int, to the 8-byte quantity (note: this is not the real 8byte quantity, just the same amount that scsilun_to_int() was able to convert and store originally). This also solves the dilemma of the thread: http://marc.theaimsgroup.com/?l=linux-kernel&m=112116767118981&w=2 A patch for the lpfc driver to use this function will be along in a few days (batched with other patches).

2005-07-14[SCSI] qla2xxx: Cleanup FC remote port registration.Andrew Vasquez
Cleanup FC remote port registration. Due to the inherent behaviour (an immediate scan) of adding a 'target'-role-capable rport via fc_remote_port_add(), split the registration into two steps -- addition as unknown-type role, then use fc_remote_port_rolchg() with appropriate role (based on PLOGI/PRLI bits). This allows for a more cleaner rport->dd_data management as can be seen with the simplified qla2xxx_slave_alloc() function.
