ocfs2_resmap_restart(9) 💅✨

okay so this page is from the Kernel API Manual, and it’s literally about “restart”ing a reservation bitmap. bestie, it’s giving kernel-internals main character energy, and the details are all below 🫶

NAME 🎀

ocfs2_resmap_restart - "restart" a reservation bitmap

SYNOPSIS 🌸

void ocfs2_resmap_restart (struct ocfs2_reservation_map *resmap ,
unsigned int clen , char *disk_bitmap );

ARGUMENTS 🫶

• resmap — the reservations bitmap. yes, that’s the whole vibe.
• clen — the Number of valid bits in the bitmap. count ’em, bestie.
• disk_bitmap — the disk bitmap this resmap should refer to.

DESCRIPTION 💖

Basically: re-initialize the parameters of a reservation bitmap. This is useful for local alloc window slides, iykyk. ✨

Also, heads up: this function will call ocfs2_trunc_resv against all existing reservations. A future version will recalculate existing reservations based on the new bitmap — that’s the future-plan tea, fr fr. 🍓
