[LTP] [PATCH v8 2/2] fstat: add test for multiple file types using fstat

[Andrea Cervesato]

Hi Jinseok,

> +	int flags = O_RDONLY | O_NONBLOCK;

consider using O_PATH instead of O_RDONLY | O_NONBLOCK for device
nodes. fstat() works correctly on O_PATH file descriptors and returns
the right st_mode, without needing the underlying driver to be
present. Please use it in the SAFE_OPEN().

The test does not gate on CONFIG_BLK_DEV_LOOP via .needs_kconfigs,
so SAFE_OPEN will TBROK on systems without loop support.
