| 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

33 fiemap interface to grow in the future but without losing
59 which userspace must allocate along with the fiemap structure. The
