[LTP] [PATCH 0/3] Add tst_iterate_fd()

[Cyril Hrubis]

 - adds tst_iterate_fd() functionality
 - make use of tst_iterate_fd() in readahead01
 - add accept03 test which uses tst_iterate_fd()

This is a prototype for how the functionality to iterate over different
file descriptors should look like it converts one tests and adds
another. There is plenty of other syscalls that can use this kind of
testing, e.g. all fooat() syscalls where we can pass invalid dir_fd, the
plan is to add these if/once we agree on the API.

Cyril Hrubis (3):
  lib: Add tst_fd_iterate()
  syscalls/readahead01: Make use of tst_fd_iterate()
  syscalls: accept: Add tst_fd_iterate() test
