Delete successive tests to the same location. The code tested the result of a previous allocation, that itself was already tested. It is changed to test the result of the most recent allocation. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/ ) // <smpl> @s exists@ local idexpression y; expression x,e; @@ *if ( \(x == NULL\|IS_ERR(x)\|y != 0\) ) { ... when forall return ...; } ... when != \(y = e\|y += e\|y -= e\|y |= e\|y &= e\|y++\|y--\|&y\) when != \(XT_GETPAGE(...,y)\|WMI_CMD_BUF(...)\) *if ( \(x == NULL\|IS_ERR(x)\|y != 0\) ) { ... when forall return ...; } // </smpl> Signed-off-by:

Boot from SAN fails in some cases where boot target login response is slow. In this case, probe finishes early and triggers init, which doesn't find remote disk to mount root which leads to BFS failure. Signed-off-by:

Problem: If initialization of adapter fails for some reason, then the interrupt handlers are released. The interrupt handlers are not registered again when initialization of adapter is retried. Solution: Re-register the interrupt handler when adapter initialization is retried. Signed-off-by:

Problem: QLA4xxx firmware may assert if given more IOCBs than it can handle. Solution: The driver was updated to throttle the number of active IOCBs based on the total number of IOCB buffers received from get_firmware_status mbx_sts[2]. Signed-off-by:

The spurious interrupt messages are seen when interrupt lines are shared between different adapters or modules. Example, interrupt lines are shared between qlcnic and qla4xxx and USB modules, then the console is flooded with flurry of spurious interrupt messages which are expected in such scenario. Hence put these messages under debug level 2 for INTx interrupt mode. Signed-off-by:

When doing a hotplug remove of a cxgb4 device, there are still dandling symlinks at /sys/class/scsi_host/hostX to the removed PCI device. The upper layer device may also try to send data, which may crash the system. The DETACH message from the lower level driver is sent to the ULD when the device is removed, when the scsi host should be removed from the system, avoiding any problems. After this patch, there are no more dangling symlinks and many attempts to crash the system while there is SCSI activity and removing the device have failed. Adding the device back again works as expected, with the scsi hosts showing up again. Based on a patch by Karen Xie. Signed-off-by:
