section mismatches gone wild
Greetings all, from your resident old fart; I have built 2.6.35.1 about 6 or 7 times, looking for the reason its not loading microcode correctly for either my AMD phenom, or my radeon video card.

vfs: introduce FS_IOC_SYNCFS to sync a single super
On Monday 09 August 2010, Sage Weil wrote: Currently the only way to sync a single super_block (and not all of them via sync(2)) is via the BLKFLSBUF ioctl on the block device. That also invalidates the bdev mapping, which isn't usually desireable, and it doesn't work for non-block file systems. The ab... 9 Aug 2010 15:40

[PATCH 5/8] v5 Allow memory_block to span multiple memory sections
Update the memory sysfs code that each sysfs memory directory is now considered a memory block that can contain multiple memory sections per memory block.
