The codeflow right now is very very gnarly in a lot of places which
obviously isn't your fault. But start_creating() and end_creating()
would very naturally lend themselves to be CLASS() guards.

Unrelated: I'm very inclined to slap a patch on top that renames
start_creating()/end_creating() and start_dirop()/end_dirop() to
vfs_start_creating()/vfs_end_creating() and
vfs_start_dirop()/vfs_end_dirop(). After all they are VFS level
maintained helpers and I try to be consistent with the naming in the
codebase making it very easy to grep.
