[LTP] [PATCH 0/4] Tests for readahead() and fadvise() on overlayfs

[Amir Goldstein]

Cyril,

The following series adds test covergae for readahead() syscall
over overlayfs file and adds test coverage for a specific
posix_fadvise() syscall advice (POSIX_FADV_WILLNEED).

So far, the posix_fadvise syscall tests in LTP only test for error
conditions, but not functionality. The functionality of the advice
POSIX_FADV_WILLNEED is indentical to readahead(), so I decided not
to duplicate the readahead functional test and add test cases to
readahead02 that use the POSIX_FADV_WILLNEED implementation.

Before I decided not to write new posix_fadvise() tests I converted
the existing tests to newlib. That is available for you as github PR:
https://github.com/linux-test-project/ltp/pull/401

Thanks,
Amir.
