Waiting for a free sbal is a operation on the qdio queue. Move the code implementing the wait to zfcp_qdio.c and rename the functions accordingly. Reviewed-by:

Move the code accessing the qdio sbales and zfcp_qdio_req struct to the zfcp_qdio files and provide helper functions for accessing the qdio related parts. Reviewed-by:

Instead of dealing with large segments in the scatter-gather lists in zfcp_qdio.c, report the limits to the upper layers. With these limits in place, the code for mapping large data blocks to multiple sbales can be removed. Reviewed-by:

Link Down -> Mark all devices missing Previously, the driver took no action on a Link Down, and waited for the I/O on a dead connection to timeout in the firmware before marking the DDB missing. Link Up -> Mark all devices online F/W will do auto login to all the devices only once. After that its the responsibility of the driver to relogin to devices whenever there is : * Any sort of connection failure or * KATO expires indicating target has logged out or * I/O times out etc. Signed-off-by: -

If cxgb3i_pdu_init() fails, then it appears that cxgb3i_iscsi_init() will not be cleaned up, leading to the iscsi transport being left registered. Fix this by adding a call to cxgb3i_iscsi_cleanup() on the error path. Signed-off-by:

The scsi/scsi.h header is normally provided by the libc (and was not exported by the kernel since 2.6.24) and has been until it was re-exported with 2.6.31. The kernel version is not userspace clean and does not appear to provide anything useable in userland over the (e)glibc version. Signed-off-by:

In the original code we dereferenced "pm8001_dev" before checking if it was null. This patch moves the dereference inside the condition. This was found by a static checker (smatch). I looked, but I couldn't tell if "pm8001_dev" dev was ever actually null. The approach in this patch seemed like the safest response. Signed-off-by:

If a command times out resulting in EH getting invoked, we wait for the aborted commands to come back after sending the abort. Shorten the amount of time we wait for these responses, to ensure we don't get stuck in EH for several minutes. Signed-off-by:

Commands which are completed by the VIOS are placed on a CRQ in kernel memory for the ibmvfc driver to process. Each CRQ entry is 16 bytes. The ibmvfc driver reads the first 8 bytes to check if the entry is valid, then reads the next 8 bytes to get the handle, which is a pointer the completed command. This fixes an issue seen on Power 7 where the processor reordered the loads from memory, resulting in processing command completion with a stale handle. This could result in command timeouts, and also early completion of commands. Signed-off-by:

This patch fixes sdev_rw_attr() macro for scsi device sysfs entries. It seems there is no such function snscanf in the current linux kernel, so it fails to compile scsi driver when someone try to add a new rw entry. This has been unfixed for a long time probably because current scsi device has no rw entries. # grep snscanf . -rn ./drivers/scsi/scsi_sysfs.c:489: snscanf (buf, 20, format_string, &sdev->field); \ Signed-off-by:

This patch adds a bunch of fixes 1. Reduce sg table size to 64 (SG_MX) instead of default SG_ALL 2. clear task lists on phy down events 3. release all tasks on port deformation 4. release current task for device gone notification 5. Add sata abort handing 6. Add 10ms delay to each port reset (currently done serially and with interrupts disabled) [jejb: whitespace fixes and clean ups plus added description added dummy 94xx_clear_srs_irq function just to prevent the mismatch in the mvs_dispatch structure killing 94xx cards] Signed-off-by:Srinivas <satyasrinivasp@hcl.in> Cc: Andy Yan <ayan@marvell.com> Cc: qswang@marvell.com Cc: jfeng@marvell.com Signed-off-by:

This change is basically a clean up. datadgst_en is an int which comes from the user. I didn't see anything limiting it to 1 and 0 although obviously that's what it's supposed to be. If the user passed in 2 this test would fail. This same if condition is repeated in another function and it uses && there. Signed-off-by:

Print all world wide node names (node, port and fabric) with the same format specifier of "%16.16llx". That makes sure they all print as a 16 character hex string, with lower case letters, no 0x prefix, and without stripping off any leading 0s. Signed-off-by:

Most of the prints of fabric IDs were specified as %6x, which will not print any leading 0s. It's nice to see leading 0s for identifiers like this, which are a fixed length. This patch sets the precision modifier as well, making the specifier %6.6x, which forces the printing of leading 0s. Signed-off-by:

No reason to restrict CDB size to 12 bytes in fcoe, so increased to 16 so that 16 bytes SCSI CDB doesn't fail. Uses common define to set max_cmd_len for fcoe and fnic, fnic is already setting max_cmd_len to 16. sg_readcap -l fails without this fix. Signed-off-by:
