[PATCH v3 0/7] selftsts/ftrace: Add requires list for each test case

[Masami Hiramatsu]

Hi,

Here is the 3rd version of the series of "requires:" list for
simplifying and unifying requirement checks for each test case.

The previous version is here.

159108888259.42416.547252366885528860.stgit@devnote2">https://lkml.kernel.org/r/159108888259.42416.547252366885528860.stgit@devnote2

I've fixed a comment in the template file in this version.

In short, this series introduces "requires:" line instead of
checking required ftrace interfaces in each test case.

The requires line supports following checks
 - tracefs interface check: Check whether the given file or directory
   in the tracefs. (No suffix) [3/7],[4/7],[5/7]
 - available tracer check: Check whether the given tracer is available
   (":tracer" suffix) [6/7]
 - README feature check: Check whether the given string is in the
   README (":README" suffix) [7/7]

This series also includes the description line fix and
unresolved -> unsupported change ([1/7] and [2/7]).

Since this series depends on following 2 commits,

commit 619ee76f5c9f ("selftests/ftrace: Return unsupported if no
 error_log file") on Shuah's Kselftest tree
commit bea24f766efc ("selftests/ftrace: Distinguish between hist
 and synthetic event checks") on Steven's Tracing tree

This can be applied on the tree which merged both of them.
Also, you can get the series from the following.

Thank you,
