Subject: [PATCH 06/12] perf trace: Use vfs_getname syscall arg beautifier in more syscalls
From: Arnaldo Carvalho de Melo <acme@...hat.com>
Those were covered and tested in this cset:
access, chdir, chmod, chown, chroot, creat, getxattr,
inotify_add_watch, lchown, lgetxattr, listxattr,
lsetxattr, mkdir, mkdirat, mknod, rmdir, faccessat,
newfstatat, openat, readlink, readlinkat, removexattr,
setxattr, statfs, swapon, swapoff, truncate, unlinkat,
utime, utimes, utimensat.
E.g.:
# trace -e statfs,access,mkdir mkdir /tmp/bla
0.285 (0.020 ms): mkdir/2799 access(filename: /etc/ld.so.preload, mode: R ) = -1 ENOENT No such file or directory
1.070 (0.032 ms): mkdir/2799 statfs(pathname: /sys/fs/selinux, buf: 0x7ffeafbdc930) = 0
1.087 (0.013 ms): mkdir/2799 statfs(pathname: /sys/fs/selinux, buf: 0x7ffeafbdc820) = 0
1.189 (0.014 ms): mkdir/2799 access(filename: /etc/selinux/config ) = 0
1.905 (0.610 ms): mkdir/2799 mkdir(pathname: /tmp/bla, mode: 511 ) = 0
