Quoting <linux/exportfs.h>: > encode_fh() should return the fileid_type on success and on error > returns 255 (if the space needed to encode fh is greater than > @max_len*4 bytes). On error @max_len contains the minimum size (in 4 > byte unit) needed to encode the file handle. ZFS was not setting max_len in the case where the handle was too small. As a result of this, the `t_name_to_handle_at.c' example in name_to_handle_at(2) did not work on ZFS. zfsctl_fid() will itself set max_len if called with a fid that is too small, so if we give zfs_fid() that behavior as well, the fix is quite easy: if the handle is too small, just use a zero-size fid instead of the handle. Tested by running t_name_to_handle_at on a normal file, a directory, a .zfs directory, and a snapshot.
