There's a race where if an event is discarded from the ring buffer and an

The default MODLIB value is composed of three variables
MODLIB = $(INSTALL_MOD_PATH)$(KERNEL_MODULE_DIRECTORY)/$(KERNELRELEASE)
However, the kernel.spec hadcodes the default value of

Hello,
DESCRIPTION
This patchset fixes old problem with hungup of both rx/tx sides and adds
test for it. This happens due to non-default SO_RCVLOWAT value and
deferred credit update in virtio/vsock. Link to previous old patchset:
https://lore.kernel.org/netdev/39b2e
Both tests are almost same, only differs in two 'if' conditions, so
implemented in a single function. Tests check, that credit update
message is sent:
1) During setting SO_RCVLOWAT value of the socket.
2) When number of 'rx_bytes' become smaller than SO_RCVLOWAT value.
Signed-off-by: Arseniy Kras
Send credit update message when SO_RCVLOWAT is updated and it is bigger
than number of bytes in rx queue. It is needed, because 'poll()' will
wait until number of bytes in rx queue will be not smaller than
SO_RCVLOWAT, so kick sender to send more data. Otherwise mutual hungup
for tx/rx is possible:

xor is not the same thing as masking a bit off.
The patch itself LGTM.
When an error happens in btt_freelist_init(), its caller
discover_arenas() will directly free arena, which makes
arena->freelist allocated in btt_freelist_init() a leaked
memory. Fix this by freeing arena->freelist in all error
handling paths of btt_freelist_init().

Documentatiion/ABI: Add ABI documentation for sys-bus-dax
dax: add a sysfs knob to control memmap_on_memory behavior
drivers/dax/bus.c
Add a sysfs knob for dax devices to control the memmap_on_memory setting
if the dax device were to be hotplugged as system memory.
The default memmap_on_memory setting for dax devices originating via
pmem or hmem is set to 'false' - i.e. no memmap_on_memory semantics, to
preserve legacy behavior.
Add the missing sysfs ABI documentation for the device DAX subsystem.
Various ABI attributes under this have been present since v5.1, and more
have been added over time. In preparation for adding a new attribute,
add this file with the historical details.
