...which just returns -EBUSY if a directory alias would be created. This is to be used by fuse mkdir to make sure that a buggy or malicious userspace filesystem doesn't do anything nasty.

2013-10-23xfs: split xfs_rtalloc.c for userspace sanityDave Chinner4-1248/+1292
xfs_rtalloc.c is partially shared with userspace. Split the file up into two parts - one that is kernel private and the other which is wholly shared with userspace.

2013-10-23xfs: decouple inode and bmap btree header filesDave Chinner73-583/+403
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.

2013-10-23xfs: decouple log and transaction headersDave Chinner75-239/+276
xfs_trans.h has a dependency on xfs_log.h for a couple of structures. Most code that does transactions doesn't need to know anything about the log, but this dependency means that they have to include xfs_log.h. Decouple the xfs_trans.h and xfs_log.h header files and clean up the includes to be in dependency order. In doing this, remove the direct include of xfs_trans_reserve.h from xfs_trans.h so that we remove the dependency between xfs_trans.h and xfs_mount.h. Hence the xfs_trans.h include can be moved to the indicate the actual dependencies other header files have on it. Note that these are kernel only header files, so this does not translate to any userspace changes at all.

2013-10-23xfs: remove unused transaction callback variablesDave Chinner1-7/+0
We don't do callbacks at transaction commit time, no do we have any infrastructure to set up or run such callbacks, so remove the variables and typedefs for these operations. If we ever need to add callbacks, we can reintroduce the variables at that time.

2013-10-23xfs: split dquot buffer operations outDave Chinner8-266/+303
Parts of userspace want to be able to read and modify dquot buffers (e.g. xfs_db) so we need to split out the reading and writing of these buffers so it is easy to shared code with libxfs in userspace.

2013-10-23xfs: unify directory/attribute format definitionsDave Chinner33-426/+437
The on-disk format definitions for the directory and attribute structures are spread across 3 header files right now, only one of which is dedicated to defining on-disk structures and their manipulation (xfs_dir2_format.h). Pull all the format definitions into a single header file - xfs_da_format.h - and switch all the code over to point at that.

2013-10-23xfs: create a shared header file for format-related informationDave Chinner54-232/+289
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.
