mtd/fs/jffs2 background.c,1.42,1.43

[David Woodhouse]

Update of /home/cvs/mtd/fs/jffs2
In directory phoenix.infradead.org:/tmp/cvs-serv17048

Modified Files:
	background.c 
Log Message:
Switch to using SIGWINCH for waking GC thread. NPTL signal code will convert SIGHUP to SIGKILL 
since we have no handler (since we have no userspace).
