[PATCH 1/2] edac: i5000: carefull error handling
-EIO is not the only error code that pci_enable_device() may return, also the set of errors can be enhanced in future. We should compare return code with zero, not with concrete error value.

Per-thread clocks are so far accessible only within the same thread group. This patch makes it possible to get this information for any thread of the same user and for a user with CAP_SYS_ADMIN capability. same_thread_group is not used anymore because if the thread is in the same thread group as 'current' then t... 21 Jul 2010 14:43

[PATCH 2/4] posix-cpu-timers: Introduction of wall clocks
Currently Linux lacks a good way to get an elapsed time of a process/thread. This patch adds the interface to obtain this piece of information. The access to the new thread/process clock is restricted according to the same rules as the access to the CPU clocks. POSIX_CLOCK_WALL occupies previously unused value ... 21 Jul 2010 14:43
