2012-11-27[SCSI] osd_uld: Add osdname & systemid sysfs at scsi_osd classBoaz Harrosh1-0/+28
This patch adds the support for the following two read-only sysfs attributes to scsi_osd class members : osdname & systemid These attributes will show up as below in sysfs class hierarchy: /sys/class/scsi_osd/osdX/osdname /sys/class/scsi_osd/osdX/systemid The osdname & systemid are OSD device attributes which uniquely identify a device on the network, while it's IP and certainly it's /dev/osdX device path might change. Userspace utilities (e.g. mkfs.exofs) can parse these attributes to identify the correct OSD in safer and faster way. (Today osd apps open each device in the system and send a attributes query for these, in order to access the user requested device) Signed-off-by: Sachin Bhamare <sbhamare@panasas.com> Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

2012-11-23of/address: sparc: Declare of_iomap as an extern function for sparc againAndreas Larsson2-1/+6
This bug-fix makes sure that of_iomap is defined extern for sparc so that the sparc-specific implementation of_iomap is once again used when including include/linux/of_address.h in a sparc context. OF_GPIO that is now available for sparc relies on this. The bug was inadvertently introduced in a850a75, "of/address: add empty static inlines for !CONFIG_OF", that added a static dummy inline for of_iomap when !CONFIG_OF_ADDRESS. However, CONFIG_OF_ADDRESS is never defined for sparc, but there is a sparc-specific implementation /arch/sparc/kernel/of_device_common.c. This fix takes the same approach as 0bce04b that solved the equivalent problem for of_address_to_resource.

2012-11-23PM / QoS: fix wrong error-checking conditionGuennadi Liakhovetski1-1/+1
dev_pm_qos_add_request() can return 0, 1, or a negative error code, therefore the correct error test is "if (error < 0)." Checking just for non-zero return code leads to erroneous setting of the req->dev pointer to NULL, which then leads to a repeated call to dev_pm_qos_add_ancestor_request() in st1232_ts_irq_handler(). This in turn leads to an Oops, when the I2C host adapter is unloaded and reloaded again because of the inconsistent state of its QoS request list.

2012-11-23block: Don't access request after it might be freedRoland Dreier1-1/+7
After we've done __elv_add_request() and __blk_run_queue() in blk_execute_rq_nowait(), the request might finish and be freed immediately. Therefore checking if the type is REQ_TYPE_PM_RESUME isn't safe afterwards, because if it isn't, rq might be gone. Instead, check beforehand and stash the result in a temporary. This fixes crashes in blk_execute_rq_nowait() I get occasionally when running with lots of memory debugging options enabled -- I think this race is usually harmless because the window for rq to be reallocated is so small.

2012-11-22ipv4: do not cache looped multicastsJulian Anastasov1-2/+5
Starting from 3.6 we cache output routes for multicasts only when using route to 224/4. For local receivers we can set RTCF_LOCAL flag depending on the membership but in such case we use maddr and saddr which are not caching keys as before. Additionally, we can not use same place to cache routes that differ in RTCF_LOCAL flag value. Fix it by caching only RTCF_MULTICAST entries without RTCF_LOCAL (send-only, no loopback). As a side effect, we avoid unneeded lookup for fnhe when not caching because multicasts are not redirected and they do not learn PMTU. Thanks to Maxime Bizon for showing the caching problems in __mkroute_output for 3.6 kernels: different RTCF_LOCAL flag in cache can lead to wrong ip_mc_output or ip_output call and the visible problem is that traffic can not reach local receivers via loopback.

2012-11-22OMAPDSS: do not fail if dpll4_m4_ck is missingAaro Koskinen1-5/+9
Do not fail if dpll4_m4_ck is missing. The clock is not there on omap24xx, so this should not be a hard error. The patch retains the functionality before the commit 185bae10 (OMAPDSS: DSS: Cleanup cpu_is_xxxx checks).

2012-11-22md/raid10: decrement correct pending counter when writing to replacement.NeilBrown1-1/+1
When a write to a replacement device completes, we carefully and correctly found the rdev that the write actually went to and the blithely called rdev_dec_pending on the primary rdev, even if this write was to the replacement. This means that any writes to an array while a replacement was ongoing would cause the nr_pending count for the primary device to go negative, so it could never be removed. This bug has been present since replacement was introduced in 3.3, so it is suitable for any -stable kernel since then.

2012-11-22md/raid10: close race that lose writes lost when replacement completes.NeilBrown1-61/+68
When a replacement operation completes there is a small window when the original device is marked 'faulty' and the replacement still looks like a replacement. The faulty should be removed and the replacement moved in place very quickly, bit it isn't instant. So the code write out to the array must handle the possibility that the only working device for some slot in the replacement - but it doesn't. If the primary device is faulty it just gives up. This can lead to corruption. So make the code more robust: if either the primary or the replacement is present and working, write to them. Only when neither are present do we give up. This bug has been present since replacement was introduced in 3.3, so it is suitable for any -stable kernel since then.

2012-11-22drm/nouveau: use the correct fence implementation for nv50Maarten Lankhorst1-1/+2
Only compile time tested, noticed nv50_fence_create was never used, so fix this. This will probably fix vblank on nv50 cards. Hopefully this is still in time for 3.7 final release. Signed-off-by: Maarten Lankhorst <maarten.lankhorst@canonical.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
