β¨ ext2_blks_to_allocate(9) β¨
okay so bestie, welcome to the Kernel API Manual π this one's a little function from the ext2 squad and honestly? it's giving "tiny but crucial." let's get into it π«Ά
πΈ NAME πΈ
ext2_blks_to_allocate β it looks up the block map and counts how many direct blocks need to be allocated for the given branch. no cap, that's the whole job π
π¦ SYNOPSIS π¦
int ext2_blks_to_allocate (Indirect * branch , int k , unsigned long
blks , int blocks_to_boundary );
π ARGUMENTS π
branchβ the chain of indirect blocks π«kβ how many blocks you need for indirect blocks (yes, blocks for blocks, we love recursion-adjacent behavior)blksβ the number of data blocks to be mappedblocks_to_boundaryβ the offset in the indirect block, iykyk
π₯ DESCRIPTION π₯
it returns the number of direct blocks to allocate. that's it, that's the vibe β¨ literally just the count, main character energy but make it a return value π
π SEE ALSO π
