Date: Tue, 03 May 2011 09:47:48 -0700 From: Allison Henderson <achender@...ux.vnet.ibm.com> To: Ext4 Developers List <linux-ext4@...r.kernel.org> Subject: Ext4 Punch Hole v6 Change Summary Hi All, Here is the latest copy of punch hole for ext4. This copy has been modified to apply on top of Yongqiang's v2 patch set that revises the split extents routines. So the patch that used to modify the split extents routines (patch 2/6 of punch hole v5) has been removed. I have tested this combination of patch sets against the same tests I used for v5 and they all look good. Thx Yongqiang for all your work :) Some other things that changed between v5 and v6: patch 1/5: The flag that this patch adds has been changed to use new EXT4_MB flag instead of creating a new set of flags patch 5/5: New function "ext4_ext_check_cache" has been added. It is similar to ext4_ext_in_cache but it accepts a ext4_ext_cache parameter instead of a ext4_extent. After letting one of my test cases run overnight, I found a bug that was caused by the ext4_ext_in_cache routine trying to copy a ext4_ext_cache field into a ext4_extent field that was too small to contain it. So the new ext4_ext_check_cache corrects this. That's pretty much all of the changes between the sets. As always feed back is appreciated. Thx all!
