Hi Constantine,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on fuse/for-next]
[also build test ERROR on v4.18 next-20180814]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url:    https://github.com/0day-ci/linux/commits/Constantine-Shulyupin/fuse-add-max_pages-option/20180815-132537
base:   https://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git for-next
config: x86_64-rhel (attached as .config)
compiler: gcc-7 (Debian 7.3.0-16) 7.3.0
reproduce:
        # save the attached .config to linux build tree
        make ARCH=x86_64 

Note: the linux-review/Constantine-Shulyupin/fuse-add-max_pages-option/20180815-132537 HEAD a01ed7faa3c2a69ef01952ff908d28718edb056c builds fine.
      It only hurts bisectibility.

All errors (new ones prefixed by >>):

>> ERROR: "pipe_max_size" [fs/fuse/fuse.ko] undefined!
