From 7ca4be45a0255ac8f08c05491c6add2dd87dd4f8 Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Tue, 31 Jan 2012 20:19:02 -0500 Subject: [PATCH] Btrfs: don't use crc items bigger than 4KB With the big metadata blocks, we can have crc items that are much bigger than a page. There are a few places that we try to kmalloc memory to hold the items during a split. Items bigger than 4KB don't really have a huge benefit in efficiency, but they do trigger larger order allocations. This commits changes the csums to make sure they stay under 4KB. This is not a format change, just a #define to limit huge items. Signed-off-by: Chris Mason --- Reading git-format-patch failed
