    [PATCH] new helper: d_obtain_alias · 4ea3ada2
    Christoph Hellwig authored
    The calling conventions of d_alloc_anon are rather unfortunate for all
    users, and it's name is not very descriptive either.
    Add d_obtain_alias as a new exported helper that drops the inode
    reference in the failure case, too and allows to pass-through NULL
    pointers and inodes to allow for tail-calls in the export operations.
    Incidentally this helper already existed as a private function in
    libfs.c as exportfs_d_alloc so kill that one and switch the callers
    to d_obtain_alias.
