nilfs_segctor_start_timer(9)

💖 NAME 💖

nilfs_segctor_start_timer — set timer of background write ✨

okay bestie, you're reading the Kernel API Manual page for nilfs_segctor_start_timer(9), and it's giving "tiny function, very specific job." 💅

🌸 SYNOPSIS 🌸

void nilfs_segctor_start_timer (struct nilfs_sc_info *sci );

🎀 ARGUMENTS 🎀

• sci — a nilfs_sc_info. That's the whole argument list, no extra options, no secret little values, nada. 🫶

🦋 DESCRIPTION 🦋

So this function sets the timer of the background write, periodt. ✨

If the timer has already been set, it ignores the new request — like, it's already booked and busy, so your new request gets left on read. 🙈

⚠️ big warning bestie: this function MUST be called within a section locking the segment semaphore. No cap, that part is not optional. 🔥
