commit: commit 542bd137 Author: James Bottomley <James.Bottomley@HansenPartnership.com> Date: Mon Apr 21 10:57:20 2008 -0500 [SCSI] fix SLUB WARN_ON Fixed another problem in free list handling by moving list allocation from scsi_host_alloc() to scsi_add_host(). Unfortunately it introduced a new failure mode in that hosts can pass straight from alloc to put without going through add, leaving the free list uninitialised. Fix by checking shost->cmd_pool on the release path to see if it got initialised. Signed-off-by:

Due to recent device model changes it now no longer tolerates name collisions. This causes a problem for ipr whose "state" attribute collides with an identically named one in the SCSI mid-layer. Rename the ipr driver attribute to be more specific. Signed-off-by:

Newer Dell CERC firmware (>= 6.62) implement a random deletion handling compatible with the legacy megaraid driver. The legacy handling shifted the target ID by 0x80 only for I/O commands (READ/WRITE/etc), whereas megaraid_mbox shifts the target ID always if random deletion is supported. The resulted in megaraid_mbox sending an INQUIRY to the wrong channel, and not finding any devices, obviously. So we disable the random deletion support if the offending firmware is found.

Add a 'count' variable to each symbol which gets increased every time the symbol is referenced. And then modify the register definition to include counts for symbols which are referenced from the source code only and not from the sequencer code. This will give us an automatic usage count for the symbols with only minimal hand-crafting. Signed-off-by: -

Commit 63a8651f ([SCSI] qla2xxx: Correct infinite-login-retry issue.) introduced a small regression where a successful relogin would result in an fcport's loop_id to be incorrectly reset to FC_NO_LOOP_ID. Only clear-out loopid, if retries have been 'truly' exhausted. Signed-off-by:

The driver is incorrectly assuming that the 'sp' reference held in qla2[x00|4xx]_abort_command() is valid after the mailbox command is issued to abort the exchange. It is *not*, as the command may be completed during interrupt context before control is returned to the mailbox caller. Signed-off-by:

Use the more efficient read-DMA'ble-buffer mailbox commands rather than reading a single word/dword at a time. We also remove a bulk of the duplicate mailbox command-handling codes in favor of more generic read-memory() routines (qla2xxx_dump_ram() and qla24xx_dump_ram()). Signed-off-by:

The new FCP adapter statistics provide a variety of information about the virtual adapter (subchannel). In order to collect this information the zfcp driver is extended to query this information. The information provided by the new FCP adapter statistics can be fetched by reading from the following files in the sysfs filesystem /sys/class/scsi_host/host<n>/seconds_active /sys/class/scsi_host/host<n>/requests /sys/class/scsi_host/host<n>/megabytes /sys/class/scsi_host/host<n>/utilization These are the statistics on a virtual adapter (subchannel) level. The information provided is raw and not modified or interpreted by any means. No interpretation or modification of the values is done by the zfcp driver. Signed-off-by:

Way back when, when the fc_user_scan routine was created, it kept some of its original logic that walked the rport list and kicked off a scan. Unfortunately, it didn't keep any of the locking around the rport list, nor did it consider the synchronous nature of the scan invoked. The result, there are some scan requests where the rport list changes, thus a subsequent scan is called on a bogus rport structure and the system NMI's. Signed-off-by:

We're getting a WARN_ON from SLUB indicating that we're trying to free caches with in-use objects. The root cause is a new dependency in the command/sense free on unchecked_isa_dma. The WARN_ON is caused by drivers which change this in their setup after the command/sense cache is allocated. The fix is to move the allocation of this cache into scsi_add_host() so things like gdth have an opportunity to modify it between alloc and add (but *not* after). The true fix would be to move unchecked_isa_dma into the template and out of the host, so it because a truly read only variable. Signed-off-by: -

Use kvm own refcounting instead of playing with ->filp->f_count. That will allow to get rid of a lot of crap in anon_inode_getfd() and kill a race in kvm_dev_ioctl_create_vm() (file might have been closed immediately by another thread, so ->filp might point to already freed struct file when we get around to setting it).

There is not selective cr0 intercept bug. The code in the comment sets the CR0.PG bit. But KVM sets the CR4.PG bit for SVM always to implement the paged real mode. So the 'mov %eax,%cr0' instruction does not change the CR0.PG bit. Selective CR0 intercepts only occur when a bit is actually changed. So its the right behavior that there is no intercept on this instruction. Signed-off-by:
