Metadata of INode

Ref: [http://pubs.opengroup.org/onlinepubs/009604499/basedefs/sys/stat.h.html]

Fields

dev: usize

Device ID

inode: usize

Inode number

size: usize

Size in bytes

SFS Note: for normal file size is the actuate file size for directory this is count of dirent.

blk_size: usize

A file system-specific preferred I/O block size for this object. In some file system types, this may vary from file to file.

blocks: usize

Size in blocks

atime: Timespec

Time of last access

mtime: Timespec

Time of last modification

ctime: Timespec

Time of last change

type_: FileType

Type of file

mode: u16

Permission

nlinks: usize

Number of hard links

SFS Note: different from linux, “.” and “..” count in nlinks this is same as original ucore.

uid: usize

User ID

gid: usize

Group ID

rdev: usize

Raw device id e.g. /dev/null: makedev(0x1, 0x3)
