For direct splicing (or private splicing), the output may not be a file. So abstract out the handling into a specified actor function and put the data in the splice_desc structure earlier, so we can build on top of that. This is the first step in better splice handling for drivers, and also for implementing vmsplice _to_ user memory. Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

Cluster locking might have been redone because a direct write won't complete, so this needs to be reflected in the iocb. Signed-off-by: NMark Fasheh <mark.fasheh@oracle.com>

Older file systems which didn't support holes did a dumb calculation of i_blocks based on i_size. This is no longer accurate, so fix things up to take actual allocation into account. Signed-off-by: NMark Fasheh <mark.fasheh@oracle.com>

Due to the size of our group bitmaps, we'll never have a leaf node extent record with more than 16 bits worth of clusters. Split e_clusters up so that leaf nodes can get a flags field where we can mark unwritten extents. Interior nodes whose length references all the child nodes beneath it can't split their e_clusters field, so we use a union to preserve sizing there.

Since we don't zero on extend anymore, truncate needs to be fixed up to zero the part of a file between i_size and and end of it's cluster. Otherwise a subsequent extend could expose bad data. This introduced a new helper, which can be used in ocfs2_write(). Signed-off-by: NMark Fasheh <mark.fasheh@oracle.com>

Unfortunately, ocfs2 can no longer make use of generic_file_aio_write_nlock() because allocating writes will require zeroing of pages adjacent to the I/O for cluster sizes greater than page size. Implement a custom file write here, which can order page locks for zeroing. This also has the advantage that cluster locks can easily be ordered outside of the page locks. Signed-off-by: NMark Fasheh <mark.fasheh@oracle.com>

由 Mark Fasheh 提交于
Right now, file allocation for ocfs2 is done within ocfs2_extend_file(), which is either called from ->setattr() (for an i_size change), or at the top of ocfs2_file_aio_write(). Inodes on file systems with sparse file support will want to do their allocation during the actual write call. In either case the cluster locking decisions are the same. We abstract out that code into a new function, ocfs2_lock_allocators() which will be used by a later patch to enable writing to sparse files. This also provides a nice cleanup of ocfs2_extend_allocation(). Signed-off-by: NMark Fasheh <mark.fasheh@oracle.com>

由 Mark Fasheh 提交于
For ocfs2_truncate_file(), we eliminate the "simple" truncate case which no longer exists since i_size is not tied to i_clusters. In ocfs2_extend_file(), we skip the allocation / page zeroing code for file systems which understand sparse files. The core truncate code is changed to do a bottom up tree traversal. This gets abstracted out into it's own function. To make things more readable, most of the special case handling for in-inode extents from ocfs2_do_truncate() is also removed. Though write support for sparse files comes in a later patch, we at least update ocfs2_prepare_inode_for_write() to skip allocation for sparse files.

Introduce tree rotations into the b-tree code. This will allow ocfs2 to support sparse files. Much of the added code is designed to be generic (in the ocfs2 sense) so that it can later be re-used to implement large extended attributes. This patch only adds the rotation code and does minimal updates to callers of the extent api. Signed-off-by: NMark Fasheh <mark.fasheh@oracle.com>

We don't want to print anything at all in ocfs2_lookup() when getting an error from ocfs2_iget() - it could be something as innocuous as a signal being detected in the dlm. ocfs2_permission() should filter on -ENOENT which ocfs2_meta_lock() can return if the inode was deleted on another node.

Many struct inode_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.
