Revert "exofs: Set i_mapping->backing_dev_info anyway"

2011-02-17T23:14:36Z

commit 0b0abeaf3d30cec03ac6497fe978b8f7edecc5ae upstream. This reverts commit 115e19c53501edc11f730191f7f047736815ae3d. Apparently setting inode->bdi to one's own sb->s_bdi stops VFS from sending *read-aheads*. This problem was bisected to this commit. A revert fixes it. I'll investigate farther why is this happening for the next Kernel, but for now a revert. I'm sending to stable@kernel.org as well, since it exists also in 2.6.37. 2.6.36 is good and does not have this patch.

fs: add sync_inode_metadata

2010-10-26T01:18:19Z

Add a new helper to write out the inode using the writeback code, that is including the correct dirty bit and list manipulation. A few of filesystems already opencode this, and a lot of others should be using it instead of using write_inode_now which also writes out the data.

exofs: Remove inode->i_count manipulation in exofs_new_inode

2010-10-25T16:03:07Z

exofs_new_inode() was incrementing the inode->i_count and decrementing it in create_done(), in a bad attempt to make sure the inode will still be there when the asynchronous create_done() finally arrives. This was very stupid because iput() was not called, and if it was actually needed, it would leak the inode. However all this is not needed, because at exofs_evict_inode() we already wait for create_done() by waiting for the object_created event. Therefore remove the superfluous ref counting and just Thicken the comment at exofs_evict_inode() a bit. While at it change places that open coded wait_obj_created() to call the already available wrapper. CC: Dave Chinner CC: Christoph Hellwig CC: Nick Piggin Signed-off-by: Boaz Harrosh

exofs: Set i_mapping->backing_dev_info anyway

2010-10-18T18:16:02Z

Though it has been promised that inode->i_mapping->backing_dev_info is not used and the supporting code is fine. Until the pointer will default to NULL, I'd rather it points to the correct thing regardless. At least for future infrastructure coder it is a clear indication of where are the key points that inodes are initialized. I know because it took me time to find this out.

exofs: Cleaup read path in regard with read_for_write

2010-10-18T18:16:02Z

Last BUG fix added a flag to the the page_collect structure to communicate with readpage_strip. This calls for a clean up removing that flag's reincarnations in the read functions parameters. Signed-off-by: Boaz Harrosh

exofs: Fix double page_unlock BUG in write_begin/end

2010-10-08T15:26:54Z

This BUG is there since the first submit of the code, but only triggered in last Kernel. It's timing related do to the asynchronous object-creation behaviour of exofs. (Which should be investigated farther) The bug is obvious hence the fixed. Signed-off-by: Boaz Harrosh
