Debugfs : inotify, multiple calls to debugfs_create_file, remove
Hi Greg, I just had to add inotify support to my LTTng consumer so I could inform it of the presence of new CPUs (for CPU hotplug). I noticed that no notification event was being sent when a debugfs file is created from within the kernel through debugfs_create. There are probably other notifications missing, but... 24 Nov 2006 04:43

Use freezeable workqueues to avoid suspend-related XFS corruptions
Hi all. I've did some testing this afternoon with bdev freezing disabled and without any non-vanilla code to freeze kthreads (Rafael's or my older version). If I put a BUG_ON() in submit_bio for non suspend2 I/O, it catches this trace: submit_bio xfs_buf_iorequest xlog_bdstrat_cb xlog_state_release_iclog... 20 Nov 2006 20:18

[patch] Export Last Level Cache topology to userspace
Hi, right now the sysfs topology information exports things like sibling maps (which cpu is a hyperthreading peer of another) and which "linux cpus" share the physical package. The patch below adds a bitmap in the same style that exports which "linux cpus" share the last level cache. This is relevant at least fo... 19 Nov 2006 06:46

PM: suspend/resume debugging should depend on SOFTWARE_SUSPEND
Hi! When doing 'make oldconfig' we should ask about suspend/resume debug features when SOFTWARE_SUSPEND is not enabled. These are suspend-to-ram debugging features, mostly, so no, they should not depend on software suspend. NAK. Signed-off-by: Chuck Ebbert <76306.1226(a)compuserve.com> --- 2.6... 4 Dec 2006 09:23

[PATCH] Fix unprivileged user builds of initramfs
The Kconfig help for INITRAMFS_SOURCE claims that you can specify multiple space-separated sources in order to allow unprivileged users to build an image. There are two bugs in the current implementation that prevent this from working. First, we pass "file1 dir2" to the gen_initramfs_list.sh script, which it ... 19 Nov 2006 00:27

Siemens sx1: merge framebuffer support
From: Vladimir Ananiev <vovan888(a)gmail.com> Framebuffer support for Siemens SX1; this is second big patch. (Third one will be mixer/sound support). Support is simple / pretty minimal, but seems to work okay (and is somehow important for a cell phone :-). Signed-off-by: Pavel Machek <pavel(a)suse.cz> diff --git... 27 Nov 2006 21:49

ata2: EH in ADMA mode, notifier 0x0 notifier_error 0x0 gen_ctl
During my I/O load test, after about half an hour of heavy I/O on three SATAII disks the system suddenly hung for about 3 seconds. After that I checked dmesg and found the following error output: [ 4574.193809] ata2: EH in ADMA mode, notifier 0x0 notifier_error 0x0 gen_ctl 0x1501000 status 0x400 [ 4574.193826... 19 Nov 2006 11:39
