From: Theodore Ts'o Subject: [PATCH 00/23] New spin of the bigalloc patches Date: Wed, 6 Jul 2011 12:35:43 -0400 Message-ID: <1309970166-11770-1-git-send-email-tytso@mit.edu> Cc: Theodore Ts'o To: Ext4 Developers List Return-path: Received: from li9-11.members.linode.com ([67.18.176.11]:33460 "EHLO test.thunk.org" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1754744Ab1GFQgJ (ORCPT ); Wed, 6 Jul 2011 12:36:09 -0400 Sender: linux-ext4-owner@vger.kernel.org List-ID: This version of the bigalloc patch set has a bunch of fixes so that delayed allocation and i_blocks/quota works correctly, which was the major set of failures that we had been seeing. There is still are a few warnings triggering in ext4_da_reserve_space(): EXT4-fs (sdb2): ext4_da_update_reserve_space: ino 13, used 1 with only 0 reserved data caused by fsstress, but this should be much more stable. Thanks to Aditya Kali for his yeoman work to fix this problem. The next branch in e2fsprogs branch also has a number of bigalloc fixes. E2fsck should now be able to properly check bigalloc file systems, and repair many of the more common bigalloc file system corruption issues. - Ted Aditya Kali (2): ext4: Fix bigalloc quota accounting and i_blocks value ext4: add some tracepoints in ext4/extents.c Theodore Ts'o (21): ext4: read-only support for bigalloc file systems ext4: enforce bigalloc restrictions (e.g., no online resizing, etc.) ext4: convert instances of EXT4_BLOCKS_PER_GROUP to EXT4_CLUSTERS_PER_GROUP ext4: factor out block group accounting into functions ext4: split out ext4_free_blocks_after_init() ext4: bigalloc changes to block bitmap initialization functions ext4: convert block group-relative offsets to use clusters ext4: teach mballoc preallocation code about bigalloc clusters ext4: teach ext4_free_blocks() about bigalloc and clusters ext4: teach ext4_ext_map_blocks() about the bigalloc feature ext4: teach ext4_ext_truncate() about the bigalloc feature ext4: convert s_{dirty,free}blocks_counter to s_{dirty,free}clusters_counter ext4: convert the free_blocks field in s_flex_groups to be free_clusters ext4: teach ext4_statfs() to deal with clusters if bigalloc is enabled ext4: tune mballoc's default group prealloc size for bigalloc file systems ext4: enable mounting bigalloc as read/write ext4: Rename ext4_free_blks_{count,set}() to refer to clusters ext4: rename ext4_count_free_blocks() to ext4_count_free_clusters() ext4: rename ext4_free_blocks_after_init() to ext4_free_clusters_after_init() ext4: rename ext4_claim_free_blocks() to ext4_claim_free_clusters() ext4: rename ext4_has_free_blocks() to ext4_has_free_clusters() fs/ext4/balloc.c | 345 +++++++++++++++---------- fs/ext4/ext4.h | 94 +++++-- fs/ext4/ext4_extents.h | 2 + fs/ext4/extents.c | 607 ++++++++++++++++++++++++++++++++++++++++--- fs/ext4/ialloc.c | 73 +++--- fs/ext4/indirect.c | 7 + fs/ext4/inode.c | 87 +++++-- fs/ext4/ioctl.c | 33 ++- fs/ext4/mballoc.c | 290 +++++++++++++-------- fs/ext4/mballoc.h | 9 +- fs/ext4/resize.c | 10 +- fs/ext4/super.c | 151 ++++++++--- include/trace/events/ext4.h | 415 ++++++++++++++++++++++++++++- 13 files changed, 1677 insertions(+), 446 deletions(-) -- 1.7.4.1.22.gec8e1.dirty
