2.6.34 BUG on stopping md device
Hi! Ever since I upgraded to 2.6.34, I've been getting kernel bugs whenever I stop a md array. Last night I got a kernel BUG last night after stopping an md device. I had to reboot as I could not do anything with the machine. Here's the following dmesg output: Jul 29 13:17:20 lithium kernel: md: md0 stoppe... 29 Jul 2010 11:53

[PATCH 2/3] Removing conditionalizing containing exactly the same code
Found this because there's no PPC64 in um, however both branches of this ifdef contain the exactly same code (modulo comment).

[PATCH 3/3] Removing dead copy&paste code
In arch/um there's a lot of code that is copied from their original arch (but out of sync) and contains code blocks that are either dead because these options disappearedd or because the arch/x86 Kconfig stuff doesn't reach arch/um. X86_OOSTORE is a bit tricky because it's in itself seemingly available on arch/u... 29 Jul 2010 11:53

[PATCH] U6715 16550A serial driver support

[PATCH] ptrace: optimize exit_ptrace() for the likely case
(replaces ptrace-dont-run-write_locktasklist_lock-if-the-parent-doesnt-ptrace-other-processes.patch) exit_ptrace() takes tasklist_lock unconditionally. We need this lock to avoid the race with ptrace_traceme(), it acts as a barrier. Change its caller, forget_original_parent(), to call exit_ptrace() under taskli... 29 Jul 2010 11:53

writeback: prevent sync livelock with the sync_after timestamp

writeback: introduce wbc.for_sync to cover the two sync stages
On Thu 29-07-10 19:51:43, Wu Fengguang wrote: The sync() is performed in two stages: the WB_SYNC_NONE sync and the WB_SYNC_ALL sync. It is necessary to tag both stages with wbc.for_sync, so as to prevent either of them being livelocked. The basic livelock scheme will be based on the sync_after timestamp... 30 Jul 2010 02:07
