2011-04-05jbd2: fix potential memory leak on transaction commitZhang Huan
There is potential memory leak of journal head in function jbd2_journal_commit_transaction. The problem is that JBD2 will not reclaim the journal head of commit record if error occurs or journal is abotred. I use the following script to reproduce this issue, on a RHEL6 system. I found it very easy to reproduce with async commit enabled. mount /dev/sdb /mnt -o journal_checksum,journal_async_commit touch /mnt/xxx echo offline > /sys/block/sdb/device/state sync umount /mnt rmmod ext4 rmmod jbd2 Removal of the jbd2 module will make slab complaining that "cache `jbd2_journal_head': can't free all objects".

2011-04-04ext4: fix a double free in ext4_register_li_requestTao Ma
In ext4_register_li_request, we malloc a ext4_li_request and inserts it into ext4_li_info->li_request_list. In case of any error later, we free it in the end. But if we have some error in ext4_run_lazyinit_thread, the whole li_request_list will be dropped and freed in it. So we will double free this ext4_li_request. This patch just sets elr to NULL after it is inserted to the list so that the latter kfree won't double free it.

2011-04-04ext4: fix credits computing for indirect mapped filesYongqiang Yang
When writing a contiguous set of blocks, two indirect blocks could be needed depending on how the blocks are aligned, so we need to increase the number of credits needed by one. [ Also fixed a another bug which could further underestimate the number of journal credits needed by 1; the code was using integer division instead of DIV_ROUND_UP() -- tytso] Signed-off-by: Yongqiang Yang <xiaoqiangnk@gmail.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Cc: stable@kernel.org
2011-04-04ext4: remove unnecessary [cm]time update of quota fileJan Kara
It is not necessary to update [cm]time of quota file on each quota file write and it wastes journal space and IO throughput with inode writes. So just remove the updating from ext4_quota_write() and only update times when quotas are being turned off. Userspace cannot get anything reliable from quota files while they are used by the kernel anyway. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2011-03-29fs: don't use igrab() while holding i_lockDave Chinner
Fix the incorrect use of igrab() inside the i_lock in NFS and Ceph‥ If we are already holding the i_lock, we have a reference to the inode so we can safely use ihold() to gain an extra reference. This avoids hangs due to lock recursion on the i_lock now that the inode_lock is gone and igrab() uses the i_lock itself.
