Linux kernel source tree
fd07ba1680
After the last patch removing vlan_rwsem, it is an incremental step to allow ipoib to work with netdevs that require the instance lock. In several places, netdev_lock() is changed to netdev_lock_ops_to_full() which takes care of not acquiring the lock again when the netdev is already locked. In ipoib_ib_tx_timeout_work() and __ipoib_ib_dev_flush() for HEAVY flushes, the netdev lock is acquired/released. This is needed because these functions end up calling .ndo_stop()/.ndo_open() on subinterfaces, and the device may expect the netdev instance lock to be held. ipoib_set_mode() now explicitly acquires ops lock while manipulating the features, mtu and tx queues. Finally, ipoib_napi_enable()/ipoib_napi_disable() now use the *_locked variants of the napi_enable()/napi_disable() calls and optionally acquire the netdev lock themselves depending on the dev they operate on.

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 reStructuredText 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.
