Well the allocation structure used to be kmalloc'ed and free'd by this function and gfs2_alloc_get. I changed that to put it inline in the struct gfs2_inode since there didn't seem a lot of point in having it dynamically allocated. I had left this function though since it was useful to have some demarcation points in the code which showed where the structure was in use. My plan was to later add some debugging to detect any use outside of those points, hence, I'd left in this function.
It could be removed now, but I'd prefer to give it a stay of execution for a little while at least if nobody has any strong objections to that,
Steve.
