| H A D | fiemap.rst | 7 The fiemap ioctl is an efficient method for userspace to get file
8 extent mappings. Instead of block-by-block mapping (such as bmap), fiemap
15 A fiemap request is encoded within struct fiemap:
17 .. kernel-doc:: include/uapi/linux/fiemap.h
18 :identifiers: fiemap
33 fiemap interface to grow in the future but without losing
73 .. kernel-doc:: include/uapi/linux/fiemap.h
106 (via fiemap->fm_length).
167 File systems wishing to support fiemap must implement a ->fiemap callback on
