| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ipoib_mcast_restart_task() is always called from within the single-threaded IPoIB workqueue, so flushing the workqueue from within the function can lead to a recursion overflow. But since we're running in a single-threaded workqueue, we're already synchronized against other items in the workqueue, so just get rid of the flush in ipoib_mcast_restart_task().

| | | | | | | | | | | | | | | | | | | | | | | | Userspace SRQs don't have a buffer allocated for them in the kernel, so it doesn't make sense to set srq->last during initialization. In fact, this can crash trying to follow a nonexistent buffer pointer. Signed-off-by: Roland Dreier <rolandd@cisco.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In mthca_create_eq(), we call get_eqe() before setting eq->nent. This is wrong, because get_eqe() uses eq->nent. Fix this, and clean up the code a little while we're at it. (We got lucky with the current code, because eq->nent was cleared to 0, which get_eqe() made happen to do the right thing) Pointed out by Michael S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix posting first WQE for mem-free HCAs: we need to link to previous WQE even in that case. While we're at it, simplify code for Tavor-mode HCAs. We don't really need the conditional test there either; we can similarly always link to the previous WQE. Based on Michael S.

| * | [PATCH] IB/mthca: assign ACK timeout field correctlyRoland Dreier2005-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | The hardware reads the ACK timeout field from the most significant 5 bits of struct mthca_qp_path's ackto field, not the least significant bits. This fix has the driver put the timeout in the right place. Without this, we get a timeout that is 2^8 times too small. Signed-off-by: Roland Dreier <rolandd@cisco.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | this patch adds some fc host attributes and removes its equivalents from the zfcp_adapter structure and zfcp specific sysfs subtree.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Debug features (DBFs) els_dbf, cmd_dbf and abt_dbf were removed and san_dbf, hba_dbf and scsi_dbf were introduced. The erp_dbf did not change. The new traces improve debugging of problems with zfcp, scsi-stack, multipath and hardware in the SAN. san_dbf traces things like ELS and CT commands, hba_dbf saves HBA specific information of requests, and scsi_dbf saves FCP and SCSI specific information of requests. Common to all new DBFs is that they provide a so called structured view. This significantly improves readability of the traces.

| * | [SCSI] SCSI scanning and removal fixesAlan Stern2005-09-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as545) fixes the list traversals in __scsi_remove_target and scsi_forget_host. In each case the existing code list_for_each_entry_safe in an _unsafe_ manner, because the list was not protected from outside modification while the iteration was running. The new scsi_forget_host routine takes the moderately controversial step of iterating over devices for removal rather than iterating over targets. This makes more sense to me because the current scheme treats targets as second-class citizens, created and removed on demand, rather than as objects corresponding to actual hardware. (Also I couldn't figure out any safe way to iterate over the target list, since it's not so easy to tell when a target has already been removed.)

I was going to do this eventually, honest, because there's no need to unprep and reprep a command that comes in through scsi_queue_insert(). However, I decided to leave it in to exercise the scsi_unprep_request() path just to make sure it was working. What's happening, I think, is that we also use this path for retries. Since we kill and reget the command each time, the retries decrement is never seen, so we're retrying forever. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
