The pathname beautifiers so far support just one augmented pathname per syscall, so do it just for mount's first arg, later this will get fixed. With: # perf probe -l probe:vfs_getname (on getname_flags:73@acme/git/linux/fs/namei.c with pathname) # Later this will get added to augmented_syscalls.c (eBPF): In one xterm: # perf trace -e mount,umount 2687.331 ( 3.544 ms): mount/8892 mount(dev_name: /mnt, dir_name: 0x561f9ac184a0, type: 0x561f9ac1b170, flags: BIND) = 0 3912.126 ( 8.807 ms): umount/8895 umount2(name: /mnt) = 0 ^C# In the other: $ sudo mount --bind /proc /mnt $ sudo umount /mnt Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Benjamin Peterson <benjamin@python.org> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: https://lkml.kernel.org/n/tip-qsvhrm2es635cl4zicqjeth2@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
