Update of /home/cvs/mtd/fs/jffs3
In directory phoenix.infradead.org:/tmp/cvs-serv31685

Modified Files:
	debug.c debug.h fs.c gc.c nodemgmt.c read.c readinode.c scan.c 
	wbuf.c write.c 
Log Message:
Introduce DEBUG1, DEBUG2 macros. Use them instead D1() D2() style.
Introduce PARANOIA macro. Use it to decide if to call paranoid check.
Useful if want to have paranoid checks enabled but messages disabled.
