[PATCH 2/7] perf trace: Correctly handle arrays
From: Ian Munsie <imunsie(a)au1.ibm.com> Previously, perf was assuming that an array from an ftrace event was an array of longs, which will not always be the case. Additionally, long_size is not even being initialised, so it would fail to read the data and would erroneously report that the array was filled with zer... 13 May 2010 02:53

[PATCH, RFC] addjust discard request to be aligned with hwsect size to support SSDs with larger sector size
The currect blkdev_issue_discard() function assumes 512 sector size. We have seen some problem when using discard on a SSD that has larger sector size. The following patch adjusts the starting address and size of a discard request to be aligned with hwsect size. Signed-off-by: Jiaying Zhang <jiayingz(a)google.com> ... 13 May 2010 01:49

[PATCH] Staging: saa7134-go7007: replace dma_sync_single with dma_sync_single_for_cpu
dma_sync_single() is deprecated and will be removed soon. No functional change since dma_sync_single is the wrapper of dma_sync_single_for_cpu. saa7134-go7007.c is commented out but anyway let's replace it.

[PATCH] FIXED: arch/x86/kernel/hpet.c: /* FIXME: add schedule_work_on() */

[PATCH 2/2] pci: allow sysfs file owner to read device dependent config space
The PCI config space bin_attr read handler has a hardcoded CAP_SYS_ADMIN check to verify privileges before allowing a user to read device dependent config space. This is meant to protect from an unprivileged user potentially locking up the box. When assigning a PCI device directly to a guest with libvirt and KVM... 12 May 2010 23:39
