[PATCH 2/2] scsi: Preserve retry counter through scsi_prep_fn

Save / restore the retry counter in scsi_cmd in scsi_init_command. This allows us to go back through scsi_init_command for retries and not forget we are doing a retry. Signed-off-by: Brian King --- Index: linux-2.6.git/drivers/scsi/scsi_lib.c

[PATCH 1/2] scsi: Move scsi_cmd->jiffies_at_alloc initialization to allocation time

Move the initialization of scsi_cmd->jiffies_at_alloc to allocation time rather than prep time. Also ensure that jiffies_at_alloc is preserved when we go through prep. This lets us send retries through prep again and not break the overall retry timer logic in scsi_softirq_done. Suggested-by: Bart

[patch] fs, proc: unconditional cond_resched when reading smaps

If there are large numbers of hugepages to iterate while reading /proc/pid/smaps, the page walk never does cond_resched(). On archs without split pmd locks, there can be significant and observable contention on mm->page_table_lock which cause lengthy delays without rescheduling. Always
