counter_sysfs_add(9)
π« counter_sysfs_add(9) β a Kernel API Manual moment π«
okay so bestie, welcome to the Kernel API Manual entry for counter_sysfs_add β she's a little function with a big job and honestly? she ate. π
β¨ NAME β¨
counter_sysfs_add β adds Counter sysfs attributes to the device structure. that's it, that's the whole vibe. π
πΈ SYNOPSIS πΈ
int counter_sysfs_add (struct counter_device *const counter );
like, she takes exactly one thing and she returns an int. no cap. β¨
π¦ ARGUMENTS π¦
counterβ pointer to the Counter device structure π«Ά literally just a pointer to the counter device struct, that's the whole thing.
π DESCRIPTION π
so here's what's actually happening, bestie: Counter sysfs attributes get created and added to the respective device structure, so they're ready for later registration to the system. π
resource-managed memory allocation is performed by this function β yes, she allocates, she's doing the most π β and that memory should be freed when no longer needed.
how do you free it? two iconic options:
- automatically, by a
device_unregistercall π - or manually, by a
devres_release_allcall π§
don't just leave that memory hanging around, okay? she's resource-managed, not resource-ignored. β
