When read log is 0 sized, we still need to init the wait queue to avoid kernel panics if someone does decide to poll on the read log. Test: Added test for this condition, incfs_test crashes With fix, incfs_test doesn't crash Signed-off-by: Paul Lawrence <paullawrence@google.com> Bug: 152909243 Change-Id: Ic3250523bb7ddb1839f8e95852c17103e5ffb782
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
