1) Added '()' for function names in kerneldoc comments 2) Changed comment bookends from '**/' to '*/'. The comment on the the mailing list was that '**/' "is consistently unconventional. Not wrong, just odd." The Documentation/kernel-doc-nano-HOWTO.txt states that kerneldoc comment blocks should end with '**/' but most (if not all) instance I found under drivers/scsi/ were only using the '*/' so I converted to that style. 3) Removed incorrect linebreaks in kerneldoc comments where found 4) Removed a few unnecessary blank comment lines in kerneldoc comment blocks Signed-off-by: NRobert Love <robert.w.love@intel.com> Signed-off-by: NJames Bottomley <James.Bottomley@HansenPartnership.com>

If we've just created an interface and the an rport is logging in we may have a request on the wire (say PRLI). If we destroy the interface, we'll go through each rport on the disc->rports list and set each rport's state to NONE. Then the lport will reset the EM. The EM reset will send a CLOSED event to the prli_resp() handler which will notice that the state != PRLI. In this case it frees the frame pointer, decrements the refcount and unlocks the rport. The problem is that there isn't a frame in this case. It's just a pointer with an embedded error code. The free causes an Oops. This patch moves the error checking to be before the state checking.

When a sequence cannot be delivered to the target, the local port will schedule retries, While this process is in progress, if we destroy the FCoE interface, the fcoe_sw_destroy routine is entered, and the fc_exch_mgr_free(lp->emp) is called. Thus if fc_exch_alloc() is called when retrying the sequence, the mempool_alloc() will fail to allocate the exchange because the mempool of the exchange manager has already been released. This patch is to cancel any pending retry work of the local port before we start to destroy the interface. Also, when resetting the local port, we should also stop the scheduled pending retries.

The fc_fcp_complete_locked detected data underrun in this case and set the FC_DATA_UNDRUN but that was ignored by fc_io_compl for all cases including read underrun. Added code to not to ignore FC_DATA_UNDRUN for read IO and instead suggested scsi-ml to retry cmd to recover from lost data frame. Not sure if it is okay to ignore FC_DATA_UNDRUN for other case, so let code as is for other cases but removed or-ing with zero valued fsp->cdb_status for those cases.

This allows any rport ELS to retry on LS_RJT. The rport error handling would only retry on resource allocation failures and exchange timeouts. I have a target that will occasionally reject PLOGI when we do a quick LOGO/PLOGI. When a critical ELS was rejected, libfc would fail silently leaving the rport in a dead state. The retry count and delay are managed by fc_rport_error_retry. If the retry count is exceeded fc_rport_error will be called. When retrying is not the correct course of action, fc_rport_error can be called directly.

The fcoe_xmit could call fc_pause in case the pending skb queue len is larger than FCOE_MAX_QUEUE_DEPTH, the fc_pause was trying to grab lport->lp_muex to change lport->link_status and that had these issues :- 1. The fcoe_xmit was getting called with bh disabled, thus causing "BUG: scheduling while atomic" when grabbing lport->lp_muex with bh disabled. 2. fc_linkup and fc_linkdown function calls lport_enter function with lport->lp_mutex held and these enter function in turn calls fcoe_xmit to send lport related FC frame, e.g. fc_linkup => fc_lport_enter_flogi to send flogi req. In this case grabbing the same lport->lp_mutex again in fc_puase from fcoe_xmit would cause deadlock. The lport->lp_mutex was used for setting FC_PAUSE in fcoe_xmit path but FC_PAUSE bit was not used anywhere beside just setting and clear this bit in lport->link_status, instead used a separate field qfull in fc_lport to eliminate need for lport->lp_mutex to track pending queue full condition and in turn avoid above described two locking issues. Also added check for lp->qfull in fc_fcp_lport_queue_ready to trigger SCSI_MLQUEUE_HOST_BUSY when lp->qfull is set to prevent more scsi-ml cmds while lp->qfull is set. This patch eliminated FC_LINK_UP and FC_PAUSE and instead used dedicated fields in fc_lport for this, this simplified all related conditional code. Also removed fc_pause and fc_unpause functions and instead used newly added lport->qfull directly in fcoe.

When a rport goes away, libFC does a plogi which will reset exchanges at the rport. Clean exchanges at our end, both in transport and libFC.

fc_exch_mgr structure is private to fc_exch.c. To export exch_mgr_reset to transport, transport needs access to the exch manager. Change exch_mgr_reset to use lport param which is the shared structure between libFC and transport. Alternatively, fc_exch_mgr definition can be moved to libfc.h so that lport can be accessed from mp*.

This reverts commit 155b25bc, which was totally wrong - the "embedded" options still exists (very much so) even on non-embedded platforms. It's just that we don't bother with actually asking about them when we're not embedded, we just take their default values (which is usually 'y' - the options add features that may not be worth it in a constrained environment).

This is done by 1) Wake up lock waiters when we close the master file descriptor. Not when the master structure is removed, since the latter requires the waiters themselves to release the refcount on the master structure -> Deadlock. 2) Send a SIGTERM to all clients waiting for the lock. Normally these clients will get a SIGPIPE when the X server dies, but clients may also spin trying to grab the DRM lock, without getting any sort of notification.
