2007-02-12[PATCH] mark struct file_operations const 5Arjan van de Ven1-1/+1
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2006-03-26[PATCH] mempool: use common mempool kmalloc allocatorMatthew Dobson1-42/+18
This patch changes several mempool users, all of which are basically just wrappers around kmalloc(), to use the common mempool_kmalloc/kfree, rather than their own wrapper function, removing a bunch of duplicated code.

2006-03-09[SCSI] zfcp: fix device registration issuesAndreas Herrmann3-6/+12
The patch fixes following issues: (1) Replace scsi_add_device with scsi_scan_target. (Thus the rport instead of the scsi_host becomes parent of a scsi_target again.) (2) Avoid scsi_device allocation during registration of an remote port. (Would be done during fc_scsi_scan_rport.) (3) Fix queuecommand behaviour when an zfcp unit is blocked. (Call scsi_done with DID_NO_CONNECT instead of returning SCSI_MLQUEUE_DEVICE_BUSY otherwise we might end up waiting for completion in blk_execute_rq for ever.)

2006-03-02[SCSI] zfcp: correctly set this_id for hostsAndreas Herrmann1-1/+1
It fixes a bug in zfcp which provokes a race in scsi_scan.c. Finally this can lead to an Oops like: kernel BUG at fs/sysfs/symlink.c:87! Correctly set this_id for the host. Otherwise we provoke a race between scsi_target_reap_work and concurrent scsi_add_device.

2006-02-12[SCSI] zfcp: fix: avoid race between fc_remote_port_add and scsi_add_deviceAndreas Herrmann1-0/+2
Flush workqueue of a scsi host after a remote port for that host is registered at the fc transport class. Otherwise immediate registration of a scsi device on that host is racy. Signed-off-by: Andreas Herrmann <aherrman@de.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2006-02-01[PATCH] s390: Remove CVS generated informationHeiko Carstens13-26/+0
- Remove all CVS generated information like e.g. revision IDs from drivers/s390 and include/asm-s390 (none present in arch/s390). - Add newline at end of arch/s390/lib/Makefile to avoid diff message.

2006-01-14[SCSI] zfcp: transport class adaptations IIAndreas Herrmann6-38/+29
Replaced zfcp adapter attributes with fc_host attributes: fc_topology by port_type, physical_wwpn by permanent_port_name. Make use of fc_host attribute supported_speeds. Removed zfcp adapter attribute physical_s_id. Signed-off-by: Andreas Herrmann <aherrman@de.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-01-14[SCSI] zfcp: transport class adaptationsAndreas Herrmann6-64/+136
Added host stats, removed superfluous get_starget_ functions, removed some attributes from zfcp specific sysfs tree (e.g. scsi_host_no, scsi_lun, wwnn and d_id). Host stats are given for the physical adapter port not for the virtual adapter. Reset stats is implemented in the device driver.

2005-12-01[SCSI] zfcp: fix adapter initializationAndreas Herrmann2-85/+64
Fixed various problems in opening sequence of adapters which was previously changed with NPIV support: o corrected handling when exchange port data function is not supported, otherwise adapters on z900 cannot be opened anymore o corrected setup of timer for exchange port data if called from error recovery o corrected check of return code of exchange config data Signed-off-by: Andreas Herrmann <aherrman@de.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-01[SCSI] zfcp: fix spinlock initializationHeiko Carstens3-9/+14
Move initialization of locks and lists to adapter allocation function. Otherwise we might end up with some uninitialized locks, like e.g. the erp locks which only will be inititialized if an error recovery thread for an adapter will be started.
