ENUM UM_TIMETRAVEL_START_ACK(9)

💖 enum um_timetravel_start_ack — ack-time mask for start message 💖

okay so bestie, this page is literally from the Kernel API Manual, and it's about enum um_timetravel_start_ack. yes the title gets truncated to enum um_time...el_start_ack in the header because apparently even manpage typesetters run out of room 🙈. it's one of those little enum pages — tiny, but it's giving essential, yk?

✨ SYNOPSIS ✨

enum um_timetravel_start_ack {
    UM_TIMETRAVEL_START_ACK_ID

};

that's the whole thing, no cap. one enum, one member, zero drama 🎀

🌸 Constants 🌸

• UM_TIMETRAVEL_START_ACK_ID — this is the client ID that the controller allocated. like, the controller handed out an ID, and this constant is where that ID lives. that's it, that's the whole job 💅

🦋 SEE ALSO 🦋

go read these next, fr fr — they're all in the kernel file ./include/uapi/linux/um_timetravel.h:

• struct um_timetravel_msg(9)
• enum um_timetravel_shared_mem_fds(9)
• enum um_timetravel_ops(9)
• enum um_timetravel_schedshm_cap(9)
• enum um_timetravel_schedshm_flags(9)
• Time travel shared memory overview(9)
• union um_timetravel_schedshm_client(9)
• struct um_timetravel_schedshm(9)

lowkey the whole time-travel shared memory family is a vibe — start with the overview if you want the lore 🌈

mwah, that's the page 🫶 this cutie came out of ./include/uapi/linux and it's dated October 2026, and it'll be filed under enum um_time...el_start_ack(9) forever. go forth and ack those start messages, bestie — periodt 💜✨
