*	lib/lcm.c: replace include	Rasmus Villemoes	2015-02-12	1	-1/+1
\| \| \| \| \| \| \| \| \| \|	We don't need all the stuff kernel.h pulls in; just compiler.h since export.h doesn't do necessary #includes. This removes more than 100 dependencies.

*	lib/lcm.c: lcm(n,0)=lcm(0,n) is 0, not n	Rasmus Villemoes	2014-12-10	1	-4/+2
\| \| \| \| \| \| \| \| \|	Return the mathematically correct answer when an argument is 0. Signed-off-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> Cc: Martin K.

*	lib/lcm.c: ensure correct result whenever it fits	Rasmus Villemoes	2014-12-10	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \|	Ensure that lcm(a,b) returns the mathematically correct result, provided it fits in an unsigned long. The current version returns garbage if a*b overflows, even if the final result would fit. Signed-off-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> Cc: Martin K.

*	lib: reduce the use of module.h wherever possible	Paul Gortmaker	2012-03-07	1	-1/+1
\| \| \| \| \| \| \| \| \| \|	For files only using THIS_MODULE and/or EXPORT_SYMBOL, map them onto including export.h -- or if the file isn't even using those, then just delete the include. Fix up any implicit include dependencies that were being masked by module.h along the way. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
*	lib/lcm.c: quiet sparse noise	H Hartley Sweeten	2011-07-25	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \|	The symbol 'lcm' is exported to the kernel (EXPORT_SYMBOL_GPL). Pick up it's definition in <linux/lcm.h> to quiet the sparse noise: warning: symbol 'lcm' was not declared. Should it be static?

*	block: Fix overrun in lcm() and move it to lib	Martin K. Petersen	2010-03-15	1	-0/+15
	lcm() was defined to take integer-sized arguments. The supplied arguments are multiplied, however, causing us to overflow given sufficiently large input. That in turn led to incorrect optimal I/O size reporting in some cases (RAID over RAID). Switch lcm() over to unsigned long similar to gcd() and move the function from blk-settings.c to lib.
