Subject: [PATCH] libfuse: pass security context options to kernel
Mount can be used with an "-o context=" option in order to specify a
mountpoint-wide SELinux security context different from the default context
provided by the active SELinux policy.
This is useful in order to enable users to mount multiple sshfs targets under
distinct contexts, which is my main motivation for getting this patch mainlined.

From: Carlos Maiolino <cmaiolino-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>
Date: Thu, 20 Apr 2017 14:53:01 +0200
Subject: [PATCH] make buffer size match kernel max transfer size
Currently libfuse has a hardcoded buffer limit to 128kib, while fuse
kernel module has a limit up to 32 pages.
This patch changes buffer limit to match the current page size, instead
of assuming 4096 bytes pages, enabling architectures with bigger pages
to use larger buffers, improving performance.
Also, add a new macro (HEADER_SIZE) to specify the space needed to
accommodate the header, making it easier to understand why those extra
4096 bytes are needed
