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.
