[dm-devel] device-mapper ./WHATS_NEW dmeventd/dmeventd.c ...



CVSROOT:	/cvs/dm
Module name:	device-mapper
Changes by:	meyering sourceware org	2007-07-24 14:16:48

Modified files:
	.              : WHATS_NEW 
	dmeventd       : dmeventd.c 
	lib/fs         : libdevmapper.c 

Log message:
	libdevmapper, dmeventd: be paranoid about detecting write failure
	* dmeventd/dmeventd.c (_set_oom_adj): When writing to /proc/self/oom_adj,
	detect failure even if it's hidden behind ferror.  [Using dm_fclose's
	extra ferror test here is probably not needed, since the amount written
	is nowhere near BUFSIZ, but use it regardless, for consistency. ]
	* lib/fs/libdevmapper.c (do_suspend): Detect fclose failure when
	writing to suspend.
