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.

My prior cleanup missed that tcp_data_ready() has to look at SOCK_DONE. Otherwise, an application using SO_RCVLOWAT will not get EPOLLIN event if a FIN is received in the middle of expected payload. The reason SOCK_DONE is not examined in tcp_epollin_ready() is that tcp_poll() catches the FIN because tcp_fin() is also setting RCV_SHUTDOWN into sk->sk_shutdown Fixes: 05dc72ab ("tcp: factorize logic into tcp_epollin_ready()") Signed-off-by:Eric Dumazet <edumazet@google.com> Reported-by:
