The patch titled
Subject: proc: use "unsigned int" for /proc/*/stack
has been removed from the -mm tree. Its filename was
proc-use-unsigned-int-for-proc-stack.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Alexey Dobriyan <adobriyan@xxxxxxxxx>
Subject: proc: use "unsigned int" for /proc/*/stack
struct stack_trace::nr_entries is defined as "unsigned int" (YAY!)
so the iterator should be unsigned as well.
It saves 1 byte of code or something like that.
