2009-04-27[SCSI] libfc: Do not retry if the new state is not the same as old stateAbhijeet Joglekar
For instance, if there is a Plogi pending (remote port is in Plogi state), and the state changes to say NONE (because the port is being logged off), then when the Plogi resp times out, do not start a retry. This patch partially reverts an earlier patch (libfc: check for err when recv and state is incorrect), by moving the state check back to before checking for error. However, if the state does not match, then there is an additional check to see if its an error ptr or a real frame before jumping to err or out respectively.

2009-04-27[SCSI] libfc: Hold disc mutex while processing gpn ft respAbhijeet Joglekar
gpn_ft_resp processing currently does not hold the discovery lock. disc_done() thus gets called from gpn_ft_resp or from gpn_ft_parse without the lock held. This then sets disc->pending to zero or calls gpn_ft_req() without disc_lock held. - Hold disc mutex during gpn_ft resp processing - In disc_done, release the disc mutex while calling lport callback Signed-off-by: Abhijeet Joglekar <abjoglek@cisco.com> Signed-off-by: Robert Love <robert.w.love@intel.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

2009-04-27[SCSI] cxgb3i: fix cpu use abuse during writesMike Christie
When doing a lot (128) of large writes (256K) we can hit the cxgb3_snd_win check pretty easily. The driver's xmit thread then takes 100% of the cpu. The driver should not be returning -EAGAIN for this problem. It should be returing -ENOBUFS, then when the window is opened again it should queue the xmit thread (it already wakes the xmit thread).

2009-04-27[SCSI] iscsi_tcp: don't fire conn error if pdu init failsMike Christie
If a command's scsi cmd pdu setup fails then we can just fail the IO to the scsi layer. If a DATA_OUT for a R2T fails then we will want to drop the session, because it means we got a bad request from the target (iscsi protocol error). This patch has us propogate the error upwards so libiscsi_tcp or libiscsi can decide what the best action is to take. It also fixes a bug where we could try to grab the session lock while holding it, because if iscsi_tcp drops the session in the pdu setup callout the session lock is held when setting up the scsi cmd pdu.

2009-04-27[SCSI] zfcp: avoid false ERP complete due to sema raceSwen Schillig
The ERP thread is performing a task before it is executing the corresponding down on the semaphore. The response handler of the just started exchange config should wait for the completion by performing a down on this semaphore. Since this semaphore is still positive from the ERP enqueue the handler won't wait and therefore the exchange config will always fail leaving the adapter in error. The problem can be solved by performing the down on the semaphore before starting an ERP task. This is the logically correct order. Only walk the ERP loop if there is a task to perform.

2009-04-27[SCSI] sr: report more accurate drive status after closing the tray.Peter Jones
So, what's happening here is that the drive is reporting a sense of 2/4/1 ("logical unit is becoming ready") from sr_test_unit_ready(), and then we ask for the media event notification before checking that result at all. The check_media_event_descriptor() call isn't getting a check condition, but it's also reporting that the tray is closed and that there's no media. In actuality it doesn't yet know if there's media or not, but there's no way to express that in the media event status field. My current thought is that if it told us the device isn't yet ready, we should return that immediately, since there's nothing that'll tell us any more data than that reliably: Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

2009-04-26Add new HEAD_TEXT_SECTION macro.Tim Abbott
This patch is preparation for replacing all uses of ".head.text" or ".text.head" in the kernel with macros, so that the section name can later be changed without having to touch a lot of the kernel. Since some linker scripts do more complex things than referencing HEAD_TEXT, we add a HEAD_TEXT_SECTION macro that just contains the actual name. I've defined HEAD_TEXT_SECTION in a new header, include/linux/section-names.h, so that this section name only needs to appear in one place. I anticipate creating similar macro structures for a number of other section names. The long-term goal here is to be able to change the kernel's magic section names to those that are compatible with -ffunction-sections -fdata-sections. This requires renaming all magic sections with names of the form ".text.foo". Signed-off-by: Tim Abbott <tabbott@mit.edu> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-04-24PM/Hibernate: Fix waiting for image device to appear on resumeRafael J. Wysocki
Commit c751085943362143f84346d274e0011419c84202 ("PM/Hibernate: Wait for SCSI devices scan to complete during resume") added a call to scsi_complete_async_scans() to software_resume(), so that it waited for the SCSI scanning to complete, but the call was added at a wrong place. Namely, it should have been added after wait_for_device_probe(), which is called only if the image partition hasn't been specified yet. Also, it's reasonable to check if the image partition is present and only wait for the device probing and SCSI scanning to complete if it is not the case. Additionally, since noresume is checked right at the beginning of software_resume() and the function returns immediately if it's set, it doesn't make sense to check it once again later.
