[LTP] [PATCH v3 1/3] syscalls/f{get, set}xattr: Don't pass a pointer to mode argument in open

[Tudor Cretu]

Passing NULL to open as the mode parameter is undefined behaviour
as a mode_t is a numerical type, not compatible with a pointer type.
If neither O_CREAT nor O_TMPFILE is specified in flags, then the mode
argument is ignored, so just remove it in these cases.
