A flag was needed to denote which eventfs_inode was the "events" directory, so a bit was taken from the "nr_entries" field, as there's not that many entries, and 2^30 is plenty. But the bit number for nr_entries was not updated to reflect the bit taken from it, which would add an unnecessary integer to the structure.
