Struct BitmapWrite 

pub struct BitmapWrite {
    pub bitmap_block: u64,
    pub bit_start: u32,
    pub count: u32,
    pub set: bool,
}

A change to one bitmap block: flip bits bit_start .. bit_start + count from 0 (free) to 1 (used). The new bitmap bytes are NOT materialised here — only the semantic description is.

Fields

bitmap_block: u64

Physical block number of the bitmap (from bg_block_bitmap or bg_inode_bitmap).

bit_start: u32

First bit index within this bitmap to flip.

count: u32

Number of consecutive bits to flip.

set: bool

true if marking used, false if freeing.
