Subject: [PATCH v6 05/37] fs: Convert alloc_inode_sb() to a macro

From: Kent Overstreet <kent.overstreet@...ux.dev>

We're introducing alloc tagging, which tracks memory allocations by
callsite. Converting alloc_inode_sb() to a macro means allocations will
be tracked by its caller, which is a bit more useful.
