Adding new subcommand "perf lock" to perf. I made this patch series on latest perf/core of tip (ef12a141306c90336a3a10d40213ecd98624d274), so please apply this series to perf/core. Sorry for my slow work, Frederic and Ingo. I have a lot of rest ToDos, but finally perf lock can provide minimal functions for analyzing lock statistics. This patch series has a serious problem, this have to revert f5a2c3dce03621b55f84496f58adc2d1a87ca16f to work. ... Quoting description at 12/12 ... This patch is required for making "perf lock rec" work. The commit f5a2c3dce0 changes write_event() of builtin-record.c . And changed write_event() sometimes doesn't stop with perf lock rec. I'm researching what makes write_event() loop infinity, and noticed that there are some events with event_t->header.size == 0. But the detail of the problem, like kind of these events, isn't clear... If you know something related to this problem, could you tell me, Arnaldo?
