From: Poyo VL Date: Mon, 11 Oct 2010 20:45:52 +0000 (-0700) Subject: When I tried to compile I got the following warning: X-Git-Tag: v2.6.37-rc1~182^2~4 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f30d44f3e54a94e037da7a71d714b585dab28d9e;p=karo-tx-linux.git When I tried to compile I got the following warning: fs/ocfs2/slot_map.c: In function ‘ocfs2_init_slot_info’: fs/ocfs2/slot_map.c:360: warning: ‘bytes’ may be used uninitialized in this function fs/ocfs2/slot_map.c:360: note: ‘bytes’ was declared here Compiler: gcc version 4.4.3 (GCC) on Mandriva I'm not sure why this warning occurs, I think compiler don't know that variable "bytes" is initialized when it is sent by reference to ocfs2_slot_map_physical_size and it throws that ugly warning. However, a simple initialization of "bytes" variable with 0 will fix it.
