block: Allow merging of tail pages into the last segment

Hi These patches modify __bio_add_page to accept pages that extent the last bio segment. some drivers craft their buffers and rely on this behavior (see message in patch 2 for details) jan v3: Use code from __blk_recalc_rq_segments to decide whether the page is mergeable, v2: modify a

[PATCH v3 1/2] block: factor out vector mergeable decision to a helper function

Export the function so it can be used to predict segment counts without calling the recalc function. This will be used in the next patch. Signed-off-by: Jan Vesely jves...@redhat.com Cc: Alexander Viro v...@zeniv.linux.org.uk Cc: James Bottomley james.bottom...@hansenpartnership.com Cc: Jens

[PATCH v3 2/2] block: modify __bio_add_page check to accept pages that don't start a new segment

The original behavior was to refuse all pages after the maximum number of segments has been reached. However, some drivers (like st) craft their buffers to potentially require exactly max segments and multiple pages in the last segment. This patch modifies the check to allow pages that can be

RE: error handler scheduling

There are several possible reasons for SCSI command timeouts: a) the command request did not get to the SCSI target port and logical unit (e.g., error on the wire) b) logical unit is still working on the command c) the command completed, but status didn't get to the SCSI

Hi, If blk_get_requet fails here, it means that the queue is dead. It seems better to return a DEV_OFFLINED error code than the misleading TEMP_UNAVAIL. Comments? Signed-off-by: Jeff Moyer jmo...@redhat.com diff --git a/drivers/scsi/device_handler/scsi_dh_hp_sw.c

[PATCH] scsi_dh_alua: Add module parameter to allow failover to non preferred path without STPG

Currently ALUA device handler sends STPG command during failover and failback. Failover can be optimized by implicit failover (by not to sending STPG command), when 1 is passed as hwhandler parameter in multipath.conf. ex 2 alua 1. We may need to pass the parameter through module param for alua
