[PATCH] Cleanup code duplication in malloc on fallback to use another arena

[Siddhesh Poyarekar]

Hi,

While reading through the malloc code, I found that the code to find
another arena when the current arena cannot fulfil a request, is
duplicated in multiple calls.  This can be implemented in a single
function and that function called in all those places, which is what
this patch does.

The purpose of this cleanup is just to make the code a little bit
neater and hence readable. The change does not cause any regressions in
the testsuite on my Fedora 16 x86_64. OK to commit?

Regards,
Siddhesh

ChangeLog:

	* malloc/malloc.c (get_another_arena): New function that gets
	another arena for the caller to try its request on.
	(__libc_malloc): Use get_another_arena if the current arena
	cannot fulfil the request.
	(__libc_memalign): Likewise.
	(__libc_memalign): Likewise.
	(__libc_pvalloc): Likewise.
	(__libc_calloc): Likewise.
