thaw_workqueues(9)
π thaw_workqueues β the "wake up bestie, we're unfreezing" era π
okay so this is thaw_workqueues(9), straight out of the Kernel API Manual β yes the actual manual, section 9, kernel-space girlie. buckle up π
πΈ NAME
thaw_workqueues β literally the function that thaws workqueues. that's it. that's the vibe. π§β‘οΈπ§
β¨ SYNOPSIS
void thaw_workqueues (void );
no cap, she takes zero arguments and returns nothing. lowkey the most low-maintenance signature ever. π«Ά
π¦ ARGUMENTS
voidβ no arguments. nothing. nada. she doesn't want your input, she's booked and busy π
π DESCRIPTION
Thaw workqueues. π₯
Normal queueing is restored β like, the queue is back to its regular scheduled programming, main character energy restored β and all the collected frozen works get transferred over to their respective pool worklists. every single one. no work left behind. periodt. π
π CONTEXT
heads up bestie, this one's a little grabby (affectionate): she grabs and releases wq_pool_mutex, wq->mutex and pool->lock's.
ngl, that's a whole lot of locks β it's giving "she's holding every single one of the group chat's phones" π just know she's mutex-maxxing in there.
