[PATCH -mm 2/3] call_usermodehelper: simplify/fix UMH_NO_WAIT case
__call_usermodehelper(UMH_NO_WAIT) has 2 problems: - if kernel_thread() fails, call_usermodehelper_freeinfo() is not called. - for unknown reason UMH_NO_WAIT has UMH_WAIT_PROC logic, we spawn yet another thread which waits until the user mode application exits. Change the UMH_NO_WAIT code to use ... 9 Mar 2010 18:05

swiotlb: minor fixes for 2.6.35
Attached are four simple patches that clean up the SWIOTLB library a bit. There aren't that important, but I figured since I am doing some other work in that layer I might as well fix some things that looked out of place. Oh, and the first one is backwards compatible with the "old" syntax of changing SWIOTLB IOMM... 9 Mar 2010 18:05

[PATCH 2/4] swiotlb: Normalize the swiotlb_init_* function's naming syntax.
The previous function names were misleading by including "with_default_size" as the size was being passed in as argument. Change the functions names to be clear on what they do.

[2.6.34-rc1][libata] regression?
hello, with .34-rc1 i see some "stalls"; systems is frozen for say 30seconds, then comes backs to life The only clue i have is strange ATA logs that I didn't have before, see below. My disk may be dying, it's 6 years old, but i shows the messages only in .34-rc1, never in .33 or .32 If the stalls are unrelate... 9 Mar 2010 18:05

[PATCH] KGDB: add smp_mb() in synchronisation during exception handler exit
On 03/09/2010 11:20 AM, Will Deacon was caught saying: KGDB uses atomic variables and busy-wait loops to co-ordinate between multiple CPUs on an SMP system. When an exception is handled, the primary CPU executes kgdb_handle_exception() whilst the others execute kgdb_wait. There comes a point when th... 9 Mar 2010 16:56

tcp_recvmesg hang under NET_DMA
Hi, I've run into a case where using NET_DMA seems to cause a PUT to a modified ftpd to hang. AFAICT this is because the NET_DMA design queues up lots of memcpy operations, but doesn't issue or wait for them (and thus free the associated skbs) until it is time for tcp_recvmesg() to return. In a case where userla... 9 Mar 2010 16:56
