β¨ v4l2_m2m_src_buf_remove_by_buf β the Kernel API Manual, bestie edition β¨
okay so real talk, this page is from the Kernel API Manual and it's literally about yanking one specific source buffer out of the ready-buffer list. that's it. that's the whole vibe. π
πΈ NAME πΈ
v4l2_m2m_src_buf_remove_by_buf β take off the exact source buffer from the list of ready buffers. not a cousin, not a lookalike, the exact one. π―
β¨ SYNOPSIS β¨
void v4l2_m2m_src_buf_remove_by_buf (struct v4l2_m2m_ctx *m2m_ctx ,
struct vb2_v4l2_buffer *vbuf );
void, meaning it hands nothing back. it just does the thing and dips. π«Ά
π ARGUMENTS π
m2m_ctxβ the m2m context that's assigned to the instance, and it comes in as astruct v4l2_m2m_ctx. it's giving main character energy because everything else revolves around it. πvbufβ the buffer that's gonna get removed. the one. the chosen one. π

like, that's the whole group chat right there. iykyk. π
ngl there are no OPTIONS, no exit statuses, no env vars on this one β it's a void function, so don't go looking for a return value that isn't there. π
this little love letter to ./include/media is dated October 2026 β and yes, that's the source and the version, bestie, we put it in the sign-off because we're classy like that. πβ¨π¦ slay.
