-with support for compression and a multi-device backing store.
-.P
-There are two inode formats:
-.IP \[bu] 3
-32-byte compact with 16-bit UID/GID,
-32-bit file size,
-and no file times
-.PD 0
-.IP \[bu]
-64-byte extended with 32-bit UID/GID,
-64-bit file size,
-and a modification time
-.RI ( st_mtim ).
-.PD
-.\" See fs/erofs/super.c:shmem_parse_options for options it supports.
