okay bestie, welcome to the Kernel API Manual β¨ this one's a tiny little function page but she's lowkey important, so let's get into it π«Ά
πΈ NAME πΈ
ring_buffer_nest_end β the "okay we're done being nested, you can trace again" moment π
β¨ SYNOPSIS β¨
void ring_buffer_nest_end (struct trace_buffer *buffer );
literally that's it, that's the whole signature, no cap π
π¦ ARGUMENTS π¦
bufferβ the ring buffer you're modifying, bestie. that's the one. the whole vibe. π«Ά
π DESCRIPTION π
okay so here's the tea β β you must call this after ring_buffer_nest_start and after the ring_buffer_unlock_commit. like, it's not optional, it's not a "sure whatever" situation, it's a must fr fr π
think of it as the closing bracket to the nesting era. start it, do your thing, unlock commit it, and then nest_end it. slay. periodt π
π SEE ALSO π
all the siblings and cousins of this function live in the kernel file ./kernel/trace/ring_buffer.c β go say hi to the whole family π

and that's the whole page, icon behavior honestly π
this masterpiece dropped from ./kernel/trace in October 2026 β mwah, kisses, go trace something nested and then end it like the main character you are πππ
