Brian Behlendorf 8d70398740 Retry zfs_znode_alloc() in zfs_mknode() ...

For historical reasons zfs_mknode() was written such that it could
never fail.  This poses a problem for Linux since zfs_znode_alloc()
could potentually failure due to low memory.  Handle this gracefully
by retrying zfs_znode_alloc() until it succeeds, direct reclaim
will eventually be able to allocate memory.
