Series | [v2] Test statx syscall for SYNC_FLAGS | expand |
Hi Kewal, LGTM, bellow are some minor enhancement tips. > * statx06.c :- This could be deleted. Maybe first line of commit message "syscalls/statx: Add test for sync flags" (SYNC_FLAGS looks like a constant, which is misleading). > Testcase 1: AT_STATX_DONT_SYNC > With AT_STATX_DONT_SYNC server changes should not get sync with client. > Testcase 2: AT_STATX_FORCE_SYNC > With AT_STATX_FORCE_SYNC server changes should get sync with client. > Signed-off-by: Kewal Ukunde <kewal@zilogic.com> > Signed-off-by: Vaishnavi.d <vaishnavi.d@zilogic.com> > Signed-off-by: Tarun.T.U <tarun@zilogic.com> Reviewed-by: Petr Vorel <pvorel@suse.cz> > --- > runtest/syscalls | 1 + > testcases/kernel/syscalls/statx/.gitignore | 1 + > testcases/kernel/syscalls/statx/statx06.c | 195 +++++++++++++++++++++++++++++ > 3 files changed, 197 insertions(+) > create mode 100644 testcases/kernel/syscalls/statx/statx06.c It's needed to rename statx06.c to statx07.c (as previous was taken). ... > diff --git a/testcases/kernel/syscalls/statx/statx06.c b/testcases/kernel/syscalls/statx/statx06.c ... > +static void test_for_dont_sync(void) > +{ > + unsigned int cur_mode; > + char server_path[F_PATH_SIZE]; > + > + snprintf(server_path, sizeof(server_path), "%s/%s", SERVER_PATH, > + DONT_SYNC_FILE); > + > + get_mode(DONT_SYNC_FILE, AT_STATX_FORCE_SYNC, > + "AT_STATX_FORCE_SYNC"); > + > + SAFE_CHMOD(server_path, CURRENT_MODE); > + cur_mode = get_mode(DONT_SYNC_FILE, AT_STATX_DONT_SYNC, > + "AT_STATX_DONT_SYNC"); > + > + if (MODE(cur_mode) == DEFAULT_MODE) > + tst_res(TPASS, > + "statx() with AT_STATX_DONT_SYNC for mode %o %o", > + DEFAULT_MODE, MODE(cur_mode)); > + else > + tst_res(TFAIL, > + "statx() with AT_STATX_DONT_SYNC for mode %o %o", > + DEFAULT_MODE, MODE(cur_mode)); > +} > + > +static void test_for_force_sync(void) > +{ > + unsigned int cur_mode; > + char server_path[F_PATH_SIZE]; > + > + snprintf(server_path, sizeof(server_path), "%s/%s", SERVER_PATH, > + FORCE_SYNC_FILE); > + > + SAFE_CHMOD(server_path, CURRENT_MODE); > + cur_mode = get_mode(FORCE_SYNC_FILE, AT_STATX_FORCE_SYNC, > + "AT_STATX_FORCE_SYNC"); > + > + if (MODE(cur_mode) == CURRENT_MODE) > + tst_res(TPASS, > + "statx() with AT_STATX_FORCE_SYNC for mode %o %o", > + CURRENT_MODE, MODE(cur_mode)); > + else > + tst_res(TFAIL, > + "statx() with AT_STATX_FORCE_SYNC for mode %o %o", > + CURRENT_MODE, MODE(cur_mode)); > +} > + > +const struct test_cases { > + void (*func)(void); > +} tcases[] = { > + {test_for_dont_sync}, > + {test_for_force_sync} > +}; Both testing functions are nearly the same, why to repeat yourself?

These changes have already been made in v5 of this test case. This patch has been renamed to syscalls/statx: Add test for sync flags. Waiting for the tst_get_tmpdir() function to be ported to new library for the patch to be merged. Regards, Vaishnavi D

Hi, > ok, I'm sorry, I got confused as you're both working on the same test. > But the problem remain even on v5 [1]: missing _GNU_SOURCE definition > while > using lapi/stat.h. Sorry, I failed to check that. Have added _GNU_SOURCE definition in lapi/stat.h in patch v6. Regards, Vaishnavi D
