[REGRESSION PATCH] vsprintf: increase sizeof precision in printf_spec
Patch ef0658f3de484bf9b173639cd47544584e01efa5 changed the precision field from and int to an s8. Problem is that we have code which uses a much larger precision in the kernel. An example would in the audit code where we have: vsnprintf(...,..., " msg='%.1024s'", (char *)data); which causes precision to be to... 13 Apr 2010 21:49

Phylib polling when doing mdio_read will cause system response and transfer speed drop

[PATCH 0/6] Ceph RADOS block device
The following series implements a linux rados block device. It allows striping of data across rados, the ceph distributed block layer, and is binary compatible with Christian Brunner's kvm-rbd implementation. Similarly to the Sheepdog project, it stripes the block device across 4MB (or other configurable size) objects ... 13 Apr 2010 20:42

[REGRESSION 2.6.30][PATCH v3] sched: update load count only once per cpu in 10 tick update window
There's a period of 10 ticks where calc_load_tasks is updated by all the cpus for the load avg. Usually all the cpus do this during the first tick. If any cpus go idle, calc_load_tasks is decremented accordingly. However, if they wake up calc_load_tasks is not incremented. Thus, if cpus go idle during the 10 tick p... 13 Apr 2010 19:35

[REGRESSION bisected] Sound goes too fast due to commit 7b3a177b0
Hello, Since 2.6.34-rc*, I have a regression on alsa which prevents the sound to be played correctly. When playing, the music goes too fast, skipping some parts. Typically, it's very easy to reproduce by doing: time mplayer -endpos 30 sound-file-which-lasts-more-than-thirty-sec.mp3 If the wall clock is less th... 13 Apr 2010 18:28

[PATCH -v3 2/3] x86,pci, acpi: host bridge windows inherit BUSY flag from parent
If a host bridge window falls inside a region the architecture has marked busy, the window should inherit the busy flag so we don't try to assign that region to a device.
