Reserving file descriptors per applications
Hi, Here is the scenario: I have a shared lib which is written to profile some web servers, the lib collects some statistics from runs and logs it to files or over sockets. Some of these servers close all file descriptors under some conditions, I am not sure whether this is the right programming proactice,... 16 Jun 2010 16:35

[PATCH] perf: avoid synthesizing mmap() for all processes in per-thread mode perf record
A bug was introduced by commit c45c6ea2e5c57960dc67e00294c2b78e9540c007. Perf record was scanning /proc/PID to create synthetic PERF_RECOR_MMAP entries even though it was running in per-thread mode. There was a bogus check to select what mmaps to synthesize. We only need all processes in system-wide mode. Sign... 16 Jun 2010 15:28
