* headers: smp_lock.h reduxAlexey Dobriyan2009-07-12
| | | | | | | | | | | | | * Remove smp_lock.h from files which don't need it (including some headers!) * Add smp_lock.h to files which do need it * Make smp_lock.h include conditional in hardirq.h It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT This will make hardirq.h inclusion cheaper for every PREEMPT=n config (which includes allmodconfig/allyesconfig, BTW) Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* block: fix sg SG_DXFER_TO_FROM_DEV regressionFUJITA Tomonori2009-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I overlooked SG_DXFER_TO_FROM_DEV support when I converted sg to use the block layer mapping API (2.6.28). Douglas Gilbert explained SG_DXFER_TO_FROM_DEV: http://www.spinics.net/lists/linux-scsi/msg37135.html = The semantics of SG_DXFER_TO_FROM_DEV were: - copy user space buffer to kernel (LLD) buffer - do SCSI command which is assumed to be of the DATA_IN (data from device) variety. This would overwrite some or all of the kernel buffer - copy kernel (LLD) buffer back to the user space. The idea was to detect short reads by filling the original user space buffer with some marker bytes ("0xec" it would seem in this report). The "resid" value is a better way of detecting short reads but that was only added this century and requires co-operation from the LLD. = This patch changes the block layer mapping API to support this semantics. This simply adds another field to struct rq_map_data and enables __bio_copy_iov() to copy data from user space even with READ requests. It's better to add the flags field and kills null_mapped and the new from_user fields in struct rq_map_data but that approach makes it difficult to send this patch to stable trees because st and osst drivers use struct rq_map_data (they were converted to use the block layer in 2.6.29 and 2.6.30). Well, I should clean up the block layer mapping API. zhou sf reported this regiression and tested this patch: http://www.spinics.net/lists/linux-scsi/msg37128.html http://www.spinics.net/lists/linux-scsi/msg37168.html Reported-by: zhou sf <sxzzsf@gmail.com> Tested-by: zhou sf <sxzzsf@gmail.com> Cc: stable@kernel.org Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I recently discovered on my zalon that if the attachment fails because of a bus misconfiguration (I scrapped my HVD array, so the card is now unterminated) then the system oopses. The reason is that if ncr_attach() returns NULL (signalling failure) that NULL is passed by the goto failed straight into ncr_detach() which oopses. The fix is just to return -ENODEV in this case.

| | | | | | | | | | | | | | | The net layer might return -EAGAIN because it could not get space/mem within the sock sndtimeo or becuase the tcp/ip connection was down. For the latter we do not want to retry because the conn/session should just be shutdown and restarted. libiscsi knows the state of the session recovery so propogate this error to that layer. It will either do iscsi recovery or have us retry the operation. Right now if we have partially sent a pdu we would always retry the IO xmit slowing down recovery.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows the Adaptec firmware to pass on its values for Packetize and QAS. To do this, the settings max_iu and max_qas have been introduced into the SPI transport class and populated from the adaptec NVram tables. Domain validation in the SPI transport class will respect the max settings when configuring to the highest possible speed for testing.
