From: "Theodore Ts'o" Subject: GIT PULL] ext4 updates for 3.5 Date: Fri, 01 Jun 2012 11:07:58 -0400 Message-ID: Cc: linux-ext4@vger.kernel.org, linux-kernel@vger.kernel.org To: Linus Torvalds Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: linux-ext4.vger.kernel.org Sorry this is so late... it's been a crazily busy May... - Ted The following changes since commit 69964ea4c7b68c9399f7977aa5b9aa6539a6a98a: Linux 3.4-rc5 (2012-04-29 15:19:10 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git dev for you to fetch changes up to 5e44f8c374dc4f8eadf61cd18b2c0d46bc87c1b7: ext4: hole-punch use truncate_pagecache_range (2012-06-01 00:15:28 -0400) ---------------------------------------------------------------- Ext4 updates for 3.5 The major new feature added in this update is Darrick J. Wong's metadata checksum feature, which adds crc32 checksums to ext4's metadata fields. There is also the usual set of cleanups and bug fixes. ---------------------------------------------------------------- Akira Fujita (1): ext4: remove needs_recovery in ext4_mb_init() Andreas Dilger (1): ext4: disallow hard-linked directory in ext4_lookup Dan Carpenter (1): ext4: fix potential NULL dereference in ext4_free_inodes_counts() Darrick J. Wong (23): ext4: create a new BH_Verified flag to avoid unnecessary metadata validation ext4: change on-disk layout to support extended metadata checksumming ext4: record the checksum algorithm in use in the superblock ext4: load the crc32c driver if necessary ext4: calculate and verify superblock checksum ext4: calculate and verify inode checksums ext4: calculate and verify checksums for inode bitmaps ext4: calculate and verify block bitmap checksum ext4: verify and calculate checksums for extent tree blocks ext4: Calculate and verify checksums for htree nodes ext4: calculate and verify checksums of directory leaf blocks ext4: Calculate and verify checksums of extended attribute blocks ext4: make block group checksums use metadata_csum algorithm ext4: add checksums to the MMP block jbd2: change disk layout for metadata checksumming jbd2: enable journal clients to enable v2 checksumming jbd2: Grab a reference to the crc32c driver if necessary jbd2: checksum journal superblock jbd2: checksum revocation blocks jbd2: checksum descriptor blocks jbd2: checksum commit blocks jbd2: checksum data blocks that are stored in the journal ext4/jbd2: add metadata checksumming to the list of supported features Eric Sandeen (1): ext4: force ro mount if ext4_setup_super() fails Haogang Chen (1): ext4: fix potential integer overflow in alloc_flex_gd() Hugh Dickins (1): ext4: hole-punch use truncate_pagecache_range Salman Qazi (2): ext4: add ext4_mb_unload_buddy in the error path ext4: remove mb_groups before tearing down the buddy_cache Tao Ma (2): ext4: protect group inode free counting with group lock ext4: let getattr report the right blocks in delalloc+bigalloc Theodore Ts'o (7): ext4: remove unnecessary check in add_dirent_to_buf() ext4: enable the 64-bit jbd2 feature based on the 64-bit ext4 feature ext4: remove redundundant "(char *) bh->b_data" casts ext4: return ENOMEM when mounts fail due to lack of memory ext4: add debugging trigger for ext4_error() ext4: add missing save_error_info() to ext4_error() ext4: don't trash state flags in EXT4_IOC_SETFLAGS Wanlong Gao (1): jbd2: use kmem_cache_zalloc wrapper instead of flag Zheng Liu (3): ext4: cleanup in ext4_discard_allocated_blocks() ext4: fix format flag in ext4_ext_binsearch_idx() ext4: use consistent ssize_t type in ext4_file_write() fs/ext4/Kconfig | 2 + fs/ext4/balloc.c | 41 ++++- fs/ext4/bitmap.c | 83 +++++++++ fs/ext4/dir.c | 12 ++ fs/ext4/ext4.h | 130 +++++++++++-- fs/ext4/ext4_extents.h | 24 +++ fs/ext4/ext4_jbd2.c | 9 +- fs/ext4/ext4_jbd2.h | 7 +- fs/ext4/extents.c | 91 +++++++-- fs/ext4/file.c | 2 +- fs/ext4/ialloc.c | 81 +++++++-- fs/ext4/inode.c | 119 ++++++++++-- fs/ext4/ioctl.c | 19 +- fs/ext4/mballoc.c | 30 +-- fs/ext4/mmp.c | 44 ++++- fs/ext4/namei.c | 445 ++++++++++++++++++++++++++++++++++++++++++--- fs/ext4/resize.c | 71 +++++++- fs/ext4/super.c | 253 +++++++++++++++++++++----- fs/ext4/xattr.c | 92 ++++++++-- fs/ext4/xattr.h | 4 +- fs/jbd2/Kconfig | 2 + fs/jbd2/commit.c | 70 ++++++- fs/jbd2/journal.c | 132 +++++++++++++- fs/jbd2/recovery.c | 126 ++++++++++++- fs/jbd2/revoke.c | 27 ++- fs/jbd2/transaction.c | 4 +- include/linux/jbd2.h | 59 +++++- include/linux/jbd_common.h | 2 + 28 files changed, 1784 insertions(+), 197 deletions(-)
