All quota test-cases uses 'tests/basic/quota.c' to write data
Does sync flags have any impact?
File:tests/basic/quota.c
30 int
31 file_write (char *filename, int bs, int count)
32 {
46 fd = open (filename, O_RDWR|O_CREAT|O_SYNC, 0600);
47 while (i < count) {
48 ret = nwrite(fd, buf, bs);
49 if (ret == -1) {
50 close (fd);
51 goto out;
52 }
53 i++;
54 }
55
56 ret = fdatasync(fd);
Thanks,
Vijay
