[PATCH][RT] futex: protect against pi_blocked_on corruption during requeue PI
Thanks to Thomas, Steven, and Mike for hashing this over me. After an IRC discussion with Thomas, I put the following together. It resolves the issue for me, Mike please test and let us know if it fixes it for you. A couple of points of discussion before we commit this: The use of the new state flag, PI_WAKEUP_IN... 13 Jul 2010 04:21

[PATCH 2/2] blkdev: check for valid request queue before issuing flush
From: Dave Chinner <dchinner(a)redhat.com> Issuing a blkdev_issue_flush() on an unconfigured loop device causes a panic as q->make_request_fn is not configured. This can occur when trying to mount the unconfigured loop device as an XFS filesystem. There are no guards that catch the bio before the request function i... 13 Jul 2010 04:21
[PATCH] Support MSI Poulsbo netbook U110/U115
The MSI U110/U115's DSDT have opregion declare, but i915 drm driver does not support Poulsbo ship. It causes the acpi backlight control interface not generate by i915 drm driver. But, we are sure the MSI Poulsbo netbook U110/U115 have workable _BCM,_BQC implementation in DSDT and it control brightness by using EC ... 13 Jul 2010 04:21
[PATCH 0/2] Graceful failures for XFS on an unconfigured loop device
Run: # mount -t xfs /dev/loop0 /mnt on a freshly booted system and it won't like you anymore. This series fixes the broken XFS error handling for dispatch errors on synchronous reads that causes a hang, and then patches the panic it uncovers. With these two patches, the mount fails gracefully. The modificat... 13 Jul 2010 04:21
[PATCH 1/2] xfs: don't block on buffer read errors
From: Dave Chinner <dchinner(a)redhat.com> xfs_buf_read() fails to detect dispatch errors before attempting to wait on sychronous IO. If there was an error, it will get stuck forever, waiting for an I/O that was never started. Make sure the error is detected correctly. Further, such a failure can leave locked pa... 13 Jul 2010 04:21

[PATCH 17/50] memblock: Make memblock_find_region() out of memblock_alloc_region()
From: Benjamin Herrenschmidt <benh(a)kernel.crashing.org> This function will be used to locate a free area to put the new memblock arrays when attempting to resize them. memblock_alloc_region() is gone, the two callsites now call memblock_add_region().
