Both KASAN modes work with both SLUB and SLAB memory allocators.
For better bug detection and nicer reporting, enable CONFIG_STACKTRACE.
To augment reports with last allocation and freeing stack of the physical page,
it is recommended to enable also CONFIG_PAGE_OWNER and boot with page_owner=on.

Net DIM API exposes the main function net_dim(struct dim *dim,
struct dim_sample end_sample). This function is the entry point to the Net
DIM algorithm and has to be called every time the driver would like to check if
it should change interrupt moderation parameters. The driver should provide two
data structures: struct net_dim and struct net_dim_sample. Struct net_dim
data structures: struct dim and struct dim_sample. Struct dim
describes the state of DIM for a specific object (RX queue, TX queue,
other queues, etc.). This includes the current selected profile, previous data
samples, the callback function provided by the driver and more.

iterations under certain conditions, there is no need to moderate the net_dim()
calls as well. As mentioned above, the driver needs to provide an object of type
struct net_dim to the net_dim() function call. It is advised for each entity

help
On Cavium ThunderX2, a load, store or prefetch instruction between a
TTBR update and the corresponding context synchronizing operation can
cause a spurious Data Abort to be delivered to any hardware thread in
the CPU core.
Work around the issue by avoiding the problematic code sequence and
trapping KVM guest TTBRx_EL1 writes to EL2 when SMT is enabled. The
trap handler performs the corresponding register access, skips the
instruction and ensures context synchronization by virtue of the
exception return.
If unsure, say Y.
