Revision c110a8b792533fc1180188b91b856bb2b3390f8b authored by Linus Torvalds on 11 May 2018, 20:04:35 UTC, committed by Linus Torvalds on 11 May 2018, 20:04:35 UTC
Pull tracing fix from Steven Rostedt: "Working on some new updates to trace filtering, I noticed that the regex_match_front() test was updated to be limited to the size of the pattern instead of the full test string. But as the test string is not guaranteed to be nul terminated, it still needs to consider the size of the test string" * tag 'trace-v4.17-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Fix regex_match_front() to not over compare the test string
