Had trouble compiling on 4.6 kernel

[sautingleung]

Hi, I had trouble compiling your code on a 4.6 kernel. The foloowing is how I fixed it and finally compiled.

kernel function rename:

page_cache_release -> put_page
page_cache_get -> get_page
PAGE_CACHE_* -> PAGE_*
get_user_pages() -> get_user_pages_remote()

Interesting. Which release of the 4.6 kernel are you using?

My OS is Ubuntu 16.04. I downloaded the 4.6.2-040602-generic kernel and headers for amd64 from ubuntu's mainline ppa http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6.2-yakkety/. Your code would not compile on this kernel. Searching with google I found http://www.spinics.net/lists/reiserfs-devel/msg05026.html and torvalds/linux@1e98779. With this info I was able to hack ufsdvfs.c and ufsdjnl.c to get it to compile. I have attached those files for your perusal. Checkout http://lxr.free-electrons.com/ident?i=page_cache_get on the 4.6 kernel and see that page_cache_get is no longer in the 4.6 kernels. It surprises me you were able to compile your code on any 4.6 kernel.

Hope that helps. Please email again if you have any further questions.

Same issue here. Was installing your AUR package paragon-ufsd-dkms-git on Arch Linux for 4.6.2-1-ARCH and 4.5.7-1-ck. Module compiling for 4.5.7-1-ck succeeded while 4.6.2-1-ARCH failed. DKMS make.log attached.
