This patch series breaks up Andreas and Yu Jian's patch "fall back to
vmalloc() for large allocations" into 5 patches, with the following
changes:
1) I created new helper functions, ext4_kvmalloc(), ext4_kzalloc, and
ext4_kvfree() to simplify the code.
2) Fixed the patch so that online resize would work correctly if
s_group_info and s_group_desc were allocated using vmalloc().
(Yeah, there are other reasons why online resize won't work for
such large allocations, but let's not add to the problems; also,
there's always the possibility that kmalloc might fail for even
for a small allocation.)
3) Fixed many more places in mballoc.c where ext4_msg() would be better
than just printk().
I was waiting for Andreas and/or Yu Jian to resubmit, but since they
didn't, and I wanted these fixes, I decided to break up the patch
myself.
