libxfs: move header files

2014-06-25T04:57:36+00:00

Move all the header files that are shared with userspace into libxfs. This is done as one big chunk simpy to get it done quickly. Signed-off-by: Dave Chinner Reviewed-by: Brian Foster Signed-off-by: Dave Chinner

xfs: decouple inode and bmap btree header files

2013-10-23T21:28:49+00:00

Currently the xfs_inode.h header has a dependency on the definition of the BMAP btree records as the inode fork includes an array of xfs_bmbt_rec_host_t objects in it's definition. Move all the btree format definitions from xfs_btree.h, xfs_bmap_btree.h, xfs_alloc_btree.h and xfs_ialloc_btree.h to xfs_format.h to continue the process of centralising the on-disk format definitions. With this done, the xfs inode definitions are no longer dependent on btree header files. The enables a massive culling of unnecessary includes, with close to 200 #include directives removed from the XFS kernel code base.

xfs: create a shared header file for format-related information

2013-10-23T19:11:30+00:00

All of the buffer operations structures are needed to be exported for xfs_db, so move them all to a common location rather than spreading them all over the place. They are verifying the on-disk format, so while xfs_format.h might be a good place, it is not part of the on disk format. Hence we need to create a new header file that we centralise these related definitions. Start by moving the bffer operations structures, and then also move all the other definitions that have crept into xfs_log_format.h and xfs_format.h as there was no other shared header file to put them in.

xfs: Inode create item recovery

2013-06-27T19:26:21+00:00

When we find a icreate transaction, we need to get and initialise the buffers in the range that has been passed. Extract and verify the information in the item record, then loop over the range initialising and issuing the buffer writes delayed. Support an arbitrary size range to initialise so that in future when we allocate inodes in much larger chunks all kernels that understand this transaction can still recover them.

xfs: convert buffer verifiers to an ops structure.

2012-11-16T03:35:12+00:00

To separate the verifiers from iodone functions and associate read and write verifiers at the same time, introduce a buffer verifier operations structure to the xfs_buf. This avoids the need for assigning the write verifier, clearing the iodone function and re-running ioend processing in the read verifier, and gets rid of the nasty "b_pre_io" name for the write verifier function pointer. If we ever need to, it will also be easier to add further content specific callbacks to a buffer with an ops structure in place. We also avoid needing to export verifier functions, instead we can simply export the ops structures for those that are needed outside the function they are defined in. This patch also fixes a directory block readahead verifier issue it exposed. This patch also adds ops callbacks to the inode/alloc btree blocks initialised by growfs. These will need more work before they will work with CRCs. Signed-off-by: Dave Chinner Reviewed-by: Phil White Signed-off-by: Ben Myers
