Linus, please pull the for_linus branch for 2.6.35-rc6. git:// for_linus The kgdb validation tests found a regression where HW breakpoints stopped working with kdb / kgdb. The problem was bisected and after talking with Frederic Weisbecker a p... 28 Jul 2010 17:22

[PATCH] x86,kgdb: Fix hw breakpoint regression
HW breakpoints events stopped working correctly with kgdb as a result of commit: 018cbffe6819f6f8db20a0a3acd9bab9bfd667e4 (Merge commit 'v2.6.33' into perf/core). The regression occurred because the behavior changed for setting NOTIFY_STOP as the return value to the die notifier if the breakpoint was known to th... 28 Jul 2010 17:22
jump label v10: convert jump label to use a key
From: Jason Baron <jbaron(a)> Date: Tue, 27 Jul 2010 16:54:32 -0400 Convert the jump label code to use a key to identify each related set of jump labels instead of a string. This saves space since we no longer need to store strings and their pointers, just the keys. In addition we can simplify th... 28 Jul 2010 17:22

ext4 performance regression 2.6.27-stable versus 2.6.32 and later
Dear all, we reproducibly find significantly worse ext4 performance when our fileservers run 2.6.32 or later kernels, when compared to the 2.6.27-stable series. The hardware is RAID5 of 5 1TB WD10EACS disks (giving almost 4TB) in an external eSATA enclosure (STARDOM ST6600); disks are not partitioned but rath... 4 Aug 2010 04:55
