From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Return-Path: From: Amir Goldstein Subject: [PATCH v3 0/6] Tests for readahead() and fadvise() on overlayfs Date: Thu, 11 Oct 2018 02:34:35 +0300 Message-Id: <20181010233441.5337-1-amir73il@gmail.com> To: Cyril Hrubis Cc: ltp@lists.linux.it, Jan Stancek , Miklos Szeredi , linux-unionfs@vger.kernel.org List-ID: 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 identical to readahead() and since kernel commit 3d8f7615319b ("vfs: implement readahead(2) using POSIX_FADV_WILLNEED"), the implementations are also bound together. To add test coverage of the advice POSIX_FADV_WILLNEED, I decided not to duplicate the readahead() functional test and add test cases to readahead02 that use the POSIX_FADV_WILLNEED implementation. Thanks, Amir. Changes since v2: - Runtime check for readahead/fadvise support - Abort test case immediately if syscall fail Changes since v1: - Fix bugs in loop invocation of test (i.e. -i 2) - Address review comments from Jan Stancek - Make cached_max a global maximum over all test cases - Improve reliability of overlayfs readahead test case failure Amir Goldstein (6): syscalls/readahead01: Convert to newlib syscalls/readahead02: Convert to newlib and cleanup syscalls/readahead02: abort test if readahead syscall fails syscalls/readahead02: test readahead() on an overlayfs file syscalls/readahead02: test readahead using posix_fadvise() syscalls/readahead02: fail test if readahead did not use any cache .../kernel/syscalls/readahead/readahead01.c | 119 ++---- .../kernel/syscalls/readahead/readahead02.c | 339 +++++++++--------- 2 files changed, 198 insertions(+), 260 deletions(-) -- 2.17.1 From mboxrd@z Thu Jan 1 00:00:00 1970 From: Amir Goldstein Date: Thu, 11 Oct 2018 02:34:35 +0300 Subject: [LTP] [PATCH v3 0/6] Tests for readahead() and fadvise() on overlayfs Message-ID: <20181010233441.5337-1-amir73il@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ltp@lists.linux.it 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).
