Adhemerval Zanella Netto - Oct. 11, 2017, 8:39 p.m.
This patch follows a suggestion from Florian to add the flags on generic
API [1].

Checked on x86_64-linux-gnu.

	* bits/uio-ext.h (RWF_HIPRI, RWF_DSYNC, RWF_SYNC, RWF_NOWAIT): New
	defines.
	* sysdeps/unix/sysv/linux/bits/uio-ext.h: Fix comment format.
