more than one release, as I had it ready for the 4.0 merge window, but a last minute thing that needed to go into Linux first had to be done. That was that perf hard coded the file system number when reading /sys/kernel/debugfs/tracing directory making sure that the path had the debugfs mount # before it would parse the tracing file. This broke other use cases of perf, and the check is removed. Now when mounting /sys/kernel/debug, tracefs is automatically mounted in /sys/kernel/debug/tracing such that old tools will still see that path as expected. But now system admins can mount tracefs directly and not need to mount debugfs, which can expose security issues. A new directory is created when tracefs is configured such that system admins can now mount it separately (/sys/kernel/tracing). This branch is based off of Al Viro's vfs debugfs_automount branch at commit163f9eb95adebugfs: Provide a file creation function that also takes an initial size to get the debugfs_create_automount() operation. I just noticed that Al rebased the pull to add his Signed-off-by to that commit, and the commit is nowe59b4e9187. I did a git diff of those two and see they are the same. Only the latter has Al's SOB. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJVLA6YAAoJEEjnJuOKh9ldv6AH/1JUINDQwV+M0VTwzbLogloo Sco0byLhskmx5KLVD7Vs8BJAGrgHTdit32kzBGmLGJvVCKBa+c8lwmRw6rnXg3uX K4kGp7BIyn1/geXoGpCmDKaLGXhDcw49hRzejKDg/OqFtxKTsSeQtG8fo29ps9Do 0VaF6UDp8gYplC2N2BfpB59LVndrITQ3mSsBBeFPvS7IxFJXAhDBOq2yi0aI6HyJ ICo2L/bA9HLxMuceWrXbsun+RP68+AQlnFfAtok7AcuBzUYPCKY0shT2VMOUtpTt 1dGxMxq6q1ACfmY7gbp47WMX9aKjWcSEr0V+IYx/xex6Maf0Xsujsy99bKYUWvs= =OcgU -----END PGP SIGNATURE----- Merge tag 'trace-4.1-tracefs' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracefs from Steven Rostedt: "This adds the new tracefs file system.
