Expand description

Required superblock parameters.

This is used in NewSuperBlock::init.

Fields

magic: u32

The magic number of the superblock.

blocksize_bits: u8

The size of a block in powers of 2 (i.e., for a value of n, the size is 2^n.

maxbytes: i64

Maximum size of a file.

time_gran: u32

Granularity of c/m/atime in ns (cannot be worse than a second).
