I need to keep up with my email more. Someone asked me at my ftrace tutorial if the filters can take regex's. I told them that I don't think so. Of course, my tutorial was on 2.6.31 so I was still correct. But it would have been nice if I told them that it will in 2.6.32 or 33. -- Steve > > gedit-4941 [000] 457.735437: lock_kernel: depth: 0, fs/reiserfs/namei.c:334 reiserfs_lookup() > sync_supers-227 [001] 461.379985: lock_kernel: depth: 0, fs/reiserfs/super.c:69 reiserfs_sync_fs() > sync_supers-227 [000] 461.383096: lock_kernel: depth: 0, fs/reiserfs/journal.c:1069 flush_commit_list() > reiserfs/1-1369 [001] 461.479885: lock_kernel: depth: 0, fs/reiserfs/journal.c:3509 flush_async_commits() > > Every string is now handled as a regexp in the filter framework, which > helps to factorize the code for handling both simple strings and > regexp comparisons. > > (The regexp parsing code has been wildly cherry picked from ftrace.c > written by Steve.) > > v2: Simplify the whole and drop the filter_regex file -- To unsubscribe from this list: send the line "unsubscribe linux-tip-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
