Description

When struct dirent entries are returned by ceph_readdir() function, the field d_reclen is always 1.

Based on the documentation from man pages (from readdir and getdents/64), this field should contain the used size of the dirent structure, which include the size of the fixed fields plus the space used by the name (which may be different than the actual size of a struct dirent ).
