sched_fair.c defines print_cfs_stats, and sched_debug.c uses it, but sched.c includes both sched_fair.c and sched_debug.c, so all the references to print_cfs_stats occur in the same compilation unit. Thus, mark print_cfs_stats static. Eliminates a sparse warning: warning: symbol 'print_cfs_stats' was not declared. Should it be static?

The move_tasks() function is currently multiplexed with two distinct capabilities: 1. attempt to move a specified amount of weighted load from one run queue to another; and 2. attempt to move a specified number of tasks from one run queue to another. The first of these capabilities is used in two places, load_balance() and load_balance_idle(), and in both of these cases the return value of move_tasks() is used purely to decide if tasks/load were moved and no notice of the actual number of tasks moved is taken. The second capability is used in exactly one place, active_load_balance(), to attempt to move exactly one task and, as before, the return value is only used as an indicator of success or failure. This multiplexing of sched_task() was introduced, by me, as part of the smpnice patches and was motivated by the fact that the alternative, one function to move specified load and one to move a single task, would have led to two functions of roughly the same complexity as the old move_tasks() (or the new balance_tasks()). However, the new modular design of the new CFS scheduler allows a simpler solution to be adopted and this patch addresses that solution by: 1. adding a new function, move_one_task(), to be used by active_load_balance(); and 2. making move_tasks() a single purpose function that tries to move a specified weighted load and returns 1 for success and 0 for failure. One of the consequences of these changes is that neither move_one_task() or the new move_tasks() care how many tasks sched_class.load_balance() moves and this enables its interface to be simplified by returning the amount of load moved as its result and removing the load_moved pointer from the argument list. This helps simplify the new move_tasks() and slightly reduces the amount of work done in each of sched_class.load_balance()'s implementations. Further simplification, e.g. changes to balance_tasks(), are possible but (slightly) complicated by the special needs of load_balance_fair() so I've left them to a later patch (if this one gets accepted). NB Since move_tasks() gets called with two run queue locks held even small reductions in overhead are worthwhile. [ mingo@elte.hu ] this change also reduces code size nicely: text data bss dec hex filename 39216 3618 24 42858 a76a sched.o.before 39173 3618 24 42815 a73f sched.o.after Signed-off-by: NPeter Williams <pwil3058@bigpond.net.au> Signed-off-by: NIngo Molnar <mingo@elte.hu>

Peter Williams suggested to flip the order of update_cpu_load(rq) with the ->task_tick() call. This is a NOP for the current scheduler (the two functions are independent of each other), ->task_tick() might create some state for update_cpu_load() in the future (or in PlugSched).

check_condition code-path was similar but more complicated to Reset. It went like this: 1. extra space was allocated at aha152x_scdata for mirroring scsi_cmnd members. 2. At aha152x_internal_queue() every not check_condition (REQUEST_SENSE) command was copied to above members in case of error. 3. At busfree_run() in the DONE_CS phase if a Status of SAM_STAT_CHECK_CONDITION was detected. The command was re-queued Internally using aha152x_internal_queue(,,check_condition,) The old command members are over written with the REQUEST_SENSE info. 4. At busfree_run() in the DONE_CS phase again. If it is a check_condition command, info was restored from mirror made at first call to aha152x_internal_queue() (see 2) and the command is completed. What I did is: 1. Allocate less space in aha152x_scdata only for the 16-byte original command. (which is actually not needed by scsi-ml anymore at this stage. But this is to much knowledge of scsi-ml) 2. If Status == SAM_STAT_CHECK_CONDITION, then like before re-queue a REQUEST_SENSE command. But only now save original command members. (Less of them) 3. In aha152x_internal_queue(), just like for Reset, use the check_condition hint to set differently the working members. execute the command. 4. At busfree_run() in the DONE_CS phase again. restore needed members. While at it. This patch fixes a BUG. Old code when sending a REQUEST_SENSE for a failed command. Would than return with cmd->resid == 0 which was the status of the REQUEST_SENSE. The failing command resid was lost. And when would resid be interesting if not on a failing command?

What Reset code was doing: Save command's important/dangerous Info on stack. NULL those members from scsi_cmnd. Issue a Reset. wait for it to finish than restore members and return. What I do is save or NULL nothing. But use the "resetting" hint in aha152x_internal_queue() to NULL out working members and leave struct scsi_cmnd alone. The indent here looks funny but it will change/drop in last patch and it is clear this way what changed. Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

hunk by hunk: - CHECK_CONDITION is what happens to cmnd->status >> 1 or after status_byte() macro. But here it is used directly on status which means 0x1 which is an undefined bit in the standard. And is a status that will never return from a target. - in busfree_run at the DONE_SC phase we have 3 distinct operation: 1-if(DONE_SC->SCp.phase & check_condition) The REQUEST_SENSE command return. - Restore original command - Than continue to operation 3. 2-if(DONE_SC->SCp.Status==SAM_STAT_CHECK_CONDITION) A regular command returned with a status. - Internally re-Q a REQUEST_SENSE. - Do not do operation 3. 3- - Complete the command and return it to scsi-ml So the 0x2 in both these operations (1,2) means the scsi check-condition status, hence SAM_STAT_CHECK_CONDITION - Here the code asks about !(DONE_SC->SCp.Status & not_issued) but "not_issued" is an enum belonging to the "phase" member and not to the Status returned from target. The reason this works is because not_issued==1 and Also CHECK_CONDITION==1 (remember from hunk 1). So actually the code was asking !(DONE_SC->SCp.Status & CHECK_CONDITION). Which means "Has the status been read from target yet?" Staus is read at status_run(). "not_issued" is cleared in seldo_run() which is usually earlier than status_run(). So this patch does nothing as far as assembly is concerned but it does let the reader understand what is going on.

Our current implementation has a generic set of barrier functions that go through the SCSI driver model. Realistically, this is unnecessary, because the only device that can use barriers (sd) can set the flush functions up at probe or revalidate time. This patch pulls the barrier functions out of the mid layer and scsi driver model and relocates them directly in sd.

The device would not resume properly if it was shutdown before the system was suspended. In such scenario where the netif_running state is 0, bnx2_suspend() would not save the PCI state and so the memory enable bit and bus master enable bit would be lost. We fix this by always saving and restoring the PCI state in bnx2_suspend() and bnx2_resume() regardless of netif_running() state. Update version to 1.6.4.
