[LTP] [PATCH v2 0/3] tst_device.c: Handle Android path for backing device

[Edward Liaw]

e1b1ae66b240 ("tst_find_backing_dev: Get dev name from
/sys/dev/block/*/uevent") added a hardcoded path to check for the
backing device in /dev.  On Android, it needs to check /dev/block.

The set_dev_path function was renamed to set_dev_loop_path and its
return value was changed from 1 on success to 0 on success to be more
consistent with other functions.  A check was added to
tst_find_free_loopdev in the event that the loop device is not ready
yet, which appears to happen occasionally on Android.

v1->v2:
Changed the function signature of tst_find_backing_dev to add the length
of the path string.  Updated all references for this function to include
the added parameter.

Edward Liaw (3):
  tst_device.c: Use PATH_MAX more consistently
  set_dev_loop_path: Refactor set_dev_path and check return value
  tst_find_backing_dev: Also check /dev/block/ for backing device
