2009-09-16ext4: Replace get_ext_path macro with an inline funcitonAkira Fujita

2009-09-16ext3: Flush disk caches on fsync when neededJan Kara
In case we fsync() a file and inode is not dirty, we don't force a transaction to disk and hence don't flush disk caches. Thus file data could be just in disk caches and not on persistent storage. Fix the problem by flushing disk caches if we didn't force a transaction commit. Signed-off-by: Jan Kara <jack@suse.cz>
2009-09-16ext3: Add locking to ext3_do_update_inodeChris Mason
I've been struggling with this off and on while I've been testing the data=guarded work. The symptom is corrupted orphan lists and inodes with the wrong i_size stored on disk. I was convinced the data=guarded code was just missing a call to ext3_mark_inode_dirty, but tracing showed the i_disksize I was sending to ext3_mark_inode_dirty wasn't actually making it to the drive. ext3_mark_inode_dirty can be called without locks held (atime updates and a few others), so the data=guarded code uses locks while updating the in-memory inode, and then calls ext3_mark_inode_dirty without any locks held. But, ext3_mark_inode_dirty has no internal locking to make sure that only one CPU is updating the buffer head at a time. Generally this works out ok because everyone that changes the inode then calls ext3_mark_inode_dirty themselves. Even though it races, eventually someone updates the buffer heads and things move on. But there is still a risk of the wrong values getting in, and the data=guarded code seems to hit the race very often. Since everyone that changes the inode also logs it, it should be possible to fix this with some memory barriers. I'll leave that as an exercise to the reader and lock the buffer head instead. It it probably a good idea to have a different patch series for lockless bit flipping on the ext3 i_state field. ext3_do_update_inode &= clears EXT3_STATE_NEW without any locks held.

2009-09-16ext3: Fix possible deadlock between ext3_truncate() and ext3_get_blocks()Jan Kara
During truncate we are sometimes forced to start a new transaction as the amount of blocks to be journaled is both quite large and hard to predict. So far we restarted a transaction while holding truncate_mutex and that violates lock ordering because truncate_mutex ranks below transaction start (and it can lead to a real deadlock with ext3_get_blocks() allocating new blocks from ext3_writepage()). Luckily, the problem is easy to fix: We just drop the truncate_mutex before restarting the transaction and acquire it afterwards. We are safe to do this as by the time ext3_truncate() is called, all the page cache for the truncated part of the file is dropped and so writepage() cannot come and allocate new blocks in the part of the file we are truncating. The rest of writers is stopped by us holding i_mutex. Signed-off-by: Jan Kara <jack@suse.cz>
2009-09-16jbd: Annotate transaction start also for journal_restart()Jan Kara
lockdep annotation for a transaction start has been at the end of journal_start(). But a transaction is also started from journal_restart(). Move the lockdep annotation to start_this_handle() which covers both cases. Signed-off-by: Jan Kara <jack@suse.cz>
2009-09-16jbd: Journal block numbers can ever be only 32-bit use unsigned int for themJan Kara

2009-09-16writeback: fix possible bdi writeback refcounting problemNick Piggin
wb_clear_pending AFAIKS should not be called after the item has been put on the list, except by the worker threads. It could lead to the situation where the refcount is decremented below 0 and cause lots of problems. Presumably the !wb_has_dirty_io case is not a common one, so it can be discovered when the thread wakes up to check? Also add a comment in bdi_work_clear.

2009-09-16writeback: separate starting of sync vs opportunistic writebackJens Axboe
bdi_start_writeback() is currently split into two paths, one for WB_SYNC_NONE and one for WB_SYNC_ALL. Add bdi_sync_writeback() for WB_SYNC_ALL writeback and let bdi_start_writeback() handle only WB_SYNC_NONE. Push down the writeback_control allocation and only accept the parameters that make sense for each function. This cleans up the API considerably. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

We need to be able to pass in range_cyclic as well, so instead of growing yet another argument, split the arguments into a struct wb_writeback_args structure that we can use internally.

2009-09-15nfsd41: Backchannel: Setup sequence informationRicardo Labiaga
Follows the model used by the NFS client. Setup the RPC prepare and done function pointers so that we can populate the sequence information if minorversion == 1. rpc_run_task() is then invoked directly just like existing NFS client operations do. nfsd4_cb_prepare() determines if the sequence information needs to be setup. If the slot is in use, it adds itself to the wait queue. nfsd4_cb_done() wakes anyone sleeping on the callback channel wait queue after our RPC reply has been received. It also sets the task message result pointer to NULL to clearly indicate we're done using it.

2009-09-15nfsd4: fix null dereference creating nfsv4 callback clientJ. Bruce Fields
On setting up the callback to the client, we attempt to use the same authentication flavor the client did. We find an rpc cred to use by calling rpcauth_lookup_credcache(), which assumes that the given authentication flavor has a credentials cache. However, this is not required to be true--in particular, auth_null does not use one. Instead, we should call the auth's lookup_cred() method. Without this, a client attempting to mount using nfsv4 and auth_null triggers a null dereference. Cc: stable@kernel.org Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
