[PATCH] uml: error handling fixes
Blairsorblade noticed some confusion between our use of a system call's return value and errno. This patch fixes a number of related bugs - using errno instead of a return value using a return value instead of errno forgetting to negate a error return to get a positive error code Signed-off-by: Jeff Dike <jdike@addtoit.com> Cc: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
