Arseniy Krasnov says: ==================== allocate multiple skbuffs on tx This adds small optimization for tx path: instead of allocating single skbuff on every call to transport, allocate multiple skbuff's until credit space allows, thus trying to send as much as possible data without return to af_vsock.c. Also this patchset includes second patch which adds check and return from 'virtio_transport_get_credit()' and 'virtio_transport_put_credit()' when these functions are called with 0 argument. This is needed, because zero argument makes both functions to behave as no-effect, but both of them always tries to acquire spinlock. Moreover, first patch always calls function 'virtio_transport_put_credit()' with zero argument in case of successful packet transmission. ==================== Link: https://lore.kernel.org/r/b0d15942-65ba-3a32-ba8d-fed64332d8f6@sberdevices.ru Signed-off-by: Paolo Abeni <pabeni@redhat.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
