Biederman <ebiederm(a)xmission.com> Date: Wed Nov 4 02:50:06 2009 -0800 sysfs: Don't leak secdata when a sysfs_dirent is freed. While refreshing my sysfs patches I noticed a leak in the secdata implementation. We don't free the secdata when we free the sysfs dirent. This is a bug in 2.6.32-rc5 that we really should close.

The following commit has been merged in the linux branch: commit 89240ba059ca468ae7a8346edf7f95082458c2fc Author: Stefani Seibold <stefani(a)seibold.net> Date: Tue Nov 3 10:22:40 2009 +0100 x86, fs: Fix x86 procfs stack information for threads on 64-bit This patch fixes two issues in the procfs stack information on x86-64 linux. The 32 bit loader compat_do_execve did not store stack start. (this was figured out by Alexey Dobriyan). The stack information on a x64_64 kernel always shows 0 kbyte stack usage, because of a missing implementation of the KSTK_ESP macro which always returned -1. The new implementation now returns the right value.
