[PATCH] sisusbvga: Remove the BKL from ioctl
Seems to me that BKL is not needed here because necessary locking is already provided by mutex sisusb->lock. Also change the returned value to long.

block: don't access jiffies when initialising io_context
On Mon, Mar 01 2010, Richard Kennedy wrote: As the comment says the initial value of last_waited is never used, so there is no need to initialise it with the current jiffies. Jiffies is hot enough without accessing it for no reason. Applied, though it will not make a huge difference in any way. alloc_io_co... 1 Mar 2010 05:53

use of setjmp/longjmp in x86 emulator.
I am looking at improving KVM x86 emulator. Current code does not handle some special cases correctly (code execution from ROM, ins/outs to/from MMIO) and many exception conditions during instruction emulation are not handled correctly. There is a lot of code in emulator that is there only for exception propagation... 9 Mar 2010 02:23

[PATCH 16/16] readahead: pagecache context based mmap read-around
Do mmap read-around when there are cached pages in the nearby 256KB (covered by one radix tree node). There is a failure case though: for a sequence of page faults at page index 64*i+1, i=1,2,3,..., this heuristic will keep doing pointless read-arounds. Hopefully the pattern won't appear in real workloads. Note... 1 Mar 2010 01:32
