[LTP] [PATCH v3 0/7] syscalls: add sync device test-cases

[Sumit Garg]

This patch-set adds common test for minimal sectors written on device
for various sync related syscalls:
1. syncfs()
2. sync()
3. fsync()
4. fdatasync()
5. sync_file_range()

Also this test is run on all supported filesystems on a test block
device.

Changes in v3:
1. Scope increased from single patch to this patch-set to add common
   test for sync(), fsync(), fdatasync() and sync_file_range() syscalls.
2. Move common functionality to library functions.
3. Use %lu rather than %s while parsing sectors written.
4. Add config check for C library wrapper and fallback definition for
   syncfs() and sync_file_range() syscalls.

Changes in v2:
1. Remove unused header file include.
2. Remove redundant tst_device check.
3. Remove redundant flags from tst_test struct.
