2010-08-10new helper: end_writeback()Al Viro3-1/+14
Essentially, the minimal variant of ->evict_inode(). It's a trimmed-down clear_inode(), sans any fs callbacks. Once it returns we know that no async writeback will be happening; every ->evict_inode() instance should do that once and do that before doing anything ->write_inode() could interfere with (e.g. freeing the on-disk inode).

2010-08-10Take ->i_bdev/->i_cdev handling out of clear_inode()Al Viro1-4/+4
All call chains to clear_inode() pass through evict_inode() and clear_inode() should be called by evict_inode() exactly once. So we can pull i_bdev/i_cdev detaching up to evict_inode() itself. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2010-08-10simplify checks for I_CLEAR/I_FREEINGAl Viro11-28/+27
add I_CLEAR instead of replacing I_FREEING with it. I_CLEAR is equivalent to I_FREEING for almost all code looking at either; it's there to keep track of having called clear_inode() exactly once per inode lifetime, at some point after having set I_FREEING. I_CLEAR and I_FREEING never get set at the same time with the current code, so we can switch to setting i_flags to I_FREEING | I_CLEAR instead of I_CLEAR without loss of information. As the result of such change, checks become simpler and the amount of code that needs to know about I_CLEAR shrinks a lot. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2010-08-10xfs: new truncate sequenceChristoph Hellwig4-42/+56
Convert XFS to the new truncate sequence. We still can have errors after updating the file size in xfs_setattr, but these are real I/O errors and lead to a transaction abort and filesystem shutdown, so they are not an issue. Errors from ->write_begin and write_end can now be handled correctly because we can actually get rid of the delalloc extents while previous the buffer state was stipped in block_invalidatepage. There is still no error handling for ->direct_IO, because doing so will need some major restructuring given that we only have the iolock shared and do not hold i_mutex at all. Fortunately leaving the normally allocated blocks behind there is not a major issue and this will get cleaned up by xfs_free_eofblock later. Note: the patch is against Al's vfs.git tree as that contains the nessecary preparations. I'd prefer to get it applied there so that we can get some testing in linux-next.

2010-08-10exofs: New truncate sequenceBoaz Harrosh3-75/+42
These changes are crafted based on the similar conversion done to ext2 by Nick Piggin. * Remove the deprecated ->truncate vector. Let exofs_setattr take care of on-disk size updates. * Call truncate_pagecache on the unused pages if write_begin/end fails. * Cleanup exofs_delete_inode that did stupid inode writes and updates on an inode that will be removed. * And finally get rid of exofs_get_block. We never had any blocks it was all for calling nobh_truncate_page. nobh_truncate_page is not actually needed in exofs since the last page is complete and gone, just like all the other pages. There is no partial blocks in exofs. I've tested with this patch, and there are no apparent failures, so far.

2010-08-10check ATTR_SIZE contraints in inode_change_okChristoph Hellwig21-156/+108
Make sure we check the truncate constraints early on in ->setattr by adding those checks to inode_change_ok. Also clean up and document inode_change_ok to make this obvious. As a fallout we don't have to call inode_newsize_ok from simple_setsize and simplify it down to a truncate_setsize which doesn't return an error. This simplifies a lot of setattr implementations and means we use truncate_setsize almost everywhere. Get rid of fat_setsize now that it's trivial and mark ext2_setsize static to make the calling convention obvious. Keep the inode_newsize_ok in vmtruncate for now as all callers need an audit for its removal anyway. Note: setattr code in ecryptfs doesn't call inode_change_ok at all and needs a deeper audit, but that is left for later.

2010-08-10always call inode_change_ok early in ->setattrChristoph Hellwig6-48/+48
Make sure we call inode_change_ok before doing any changes in ->setattr, and make sure to call it even if our fs wants to ignore normal UNIX permissions, but use the ATTR_FORCE to skip those. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2010-08-10remove inode_setattrChristoph Hellwig35-194/+416
Replace inode_setattr with opencoded variants of it in all callers. This moves the remaining call to vmtruncate into the filesystem methods where it can be replaced with the proper truncate sequence. In a few cases it was obvious that we would never end up calling vmtruncate so it was left out in the opencoded variant: spufs: explicitly checks for ATTR_SIZE earlier btrfs,hugetlbfs,logfs,dlmfs: explicitly clears ATTR_SIZE earlier ufs: contains an opencoded simple_seattr + truncate that sets the filesize just above In addition to that ncpfs called inode_setattr with handcrafted iattrs, which allowed to trim down the opencoded variant.

2010-08-10default to simple_setattrChristoph Hellwig2-11/+14
With the new truncate sequence every filesystem that wants to support file size changes on disk needs to implement its own ->setattr. So instead of calling inode_setattr which supports size changes call into a simple method that doesn't support this. simple_setattr is almost what we want except that it does not mark the inode dirty after changes. Given that marking the inode dirty is a no-op for the simple in-memory filesystems that use simple_setattr currently just add the mark_inode_dirty call. Also add a WARN_ON for the presence of a truncate method to simple_setattr to catch new instances of it during the transition period.

2010-08-10rename generic_setattrChristoph Hellwig8-15/+14
Despite its name it's now a generic implementation of ->setattr, but rather a helper to copy attributes from a struct iattr to the inode. Rename it to setattr_copy to reflect this fact. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2010-08-10add missing setattr methodsChristoph Hellwig5-0/+60
For the new truncate sequence every filesystem that wants to truncate on-disk state needs a seattr method. Convert the remaining filesystems that implement the truncate inode operation to have its own setattr method.

2010-08-10get rid of block_write_begin_newtruncChristoph Hellwig13-91/+103
Move the call to vmtruncate to get rid of accessive blocks to the callers in preparation of the new truncate sequence and rename the non-truncating version to block_write_begin. While we're at it also remove several unused arguments to block_write_begin. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2010-08-10introduce __block_write_beginChristoph Hellwig10-64/+39
Split up the block_write_begin implementation - __block_write_begin is a new trivial wrapper for block_prepare_write that always takes an already allocated page and can be either called from block_write_begin or filesystem code that already has a page allocated. Remove the handling of already allocated pages from block_write_begin after switching all callers that do it to __block_write_begin.

2010-08-10clean up write_begin usage for directories in pagecacheChristoph Hellwig13-107/+57
For filesystem that implement directories in pagecache we call block_write_begin with an already allocated page for this code, while the normal regular file write path uses the default block_write_begin behaviour. Get rid of the __foofs_write_begin helper and opencode the normal write_begin call in foofs_write_begin, while adding a new foofs_prepare_chunk helper for the directory code. The added benefit is that foofs_prepare_chunk has a much saner calling convention. Note that the interruptible flag passed into block_write_begin is always ignored if we already pass in a page (see next patch for details), and we never were doing truncations of exessive blocks for this case either so we can switch directly to block_write_begin_newtrunc.

Move the call to vmtruncate to get rid of accessive blocks to the callers in prepearation of the new truncate calling sequence. This was only done for DIO_LOCKING filesystems, so the __blockdev_direct_IO_newtrunc variant was not needed anyway. Get rid of blockdev_direct_IO_no_locking and its _newtrunc variant while at it as just opencoding the two additional paramters is shorted than the name suffix.
