This is correct. fsck will actually invoke this API only once and will print
out the list of first 500 corrupted files. It will not invoke this API multiple
times. This list actually helps the adminstrator because he/she can get a
partial list of corrupted files very quickly. My theory is that this partial
list is better than waiting for a total fsck to finish which can take hours.
