To begin optimising the CIL commit process, we need to have IOP_SIZE return both the number of vectors and the size of the data pointed to by the vectors. This enables us to calculate the size ofthe memory allocation needed before the formatting step and reduces the number of memory allocations per item by one. While there, kill the IOP_SIZE macro.

xfs_attr_node_addname()'s error handling tests whether it should free "state" in the out: error handling label: out: if (state) xfs_da_state_free(state); but an earlier free doesn't set state to NULL afterwards; this could lead to a double free.

Userspace running debug builds is relatively rare, so there's need to special case the allocation algorithm code coverage debug switch.

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.

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.

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.

xfs_mount.c is shared with userspace, but the only functions that are shared are to do with physical superblock manipulations. This means that less than 25% of the xfs_mount.c code is actually shared with userspace. Move all the superblock functions to xfs_sb.c and share that instead with libxfs. Note that this will leave all the in-core transaction related superblock counter modifications in xfs_mount.c as none of that is shared with userspace. With a few more small changes, xfs_mount.h won't need to be shared with userspace anymore, either.
