2013-08-12xfs: consolidate extent swap codeDave Chinner
So we don't need xfs_dfrag.h in userspace anymore, move the extent swap ioctl structure definition to xfs_fs.h where most of the other ioctl structure definitions are. Now that we don't need separate files for extent swapping, separate the basic file descriptor checking code to xfs_ioctl.c, and the code that does the extent swap operation to xfs_bmap_util.c. This cleanly separates the user interface code from the physical mechanism used to do the extent swap.

2013-08-12xfs: kill xfs_vnodeops.[ch]Dave Chinner
Now we have xfs_inode.c for holding kernel-only XFS inode operations, move all the inode operations from xfs_vnodeops.c to this new file as it holds another set of kernel-only inode operations. The name of this file traces back to the days of Irix and it's vnodes which we don't have anymore. Essentially this move consolidates the inode locking functions and a bunch of XFS inode operations into the one file. Eventually the high level functions will be merged into the VFS interface functions in xfs_iops.c. This leaves only internal preallocation, EOF block manipulation and hole punching functions in vnodeops.c. Move these to xfs_bmap_util.c where we are already consolidating various in-kernel physical extent manipulation and querying functions.

2013-08-12xfs: create xfs_bmap_util.[ch]Dave Chinner
There is a bunch of code in xfs_bmap.c that is kernel specific and not shared with userspace. To minimise the difference between the kernel and userspace code, shift this unshared code to xfs_bmap_util.c, and the declarations to xfs_bmap_util.h. The biggest issue here is xfs_bmap_finish() - userspace has it's own definition of this function, and so we need to move it out of xfs_bmap.[ch]. This means several other files need to include xfs_bmap_util.h as well. It also introduces and interesting dance for the stack switching code in xfs_bmapi_allocate(). The stack switching/workqueue code is actually moved to xfs_bmap_util.c, so that userspace can simply use a #define in a header file to connect the dots without needing to know about the stack switch code at all.
