Linux kernel commit torvalds/linux#59d8053f moved the definition of struct proc_dir_entry from include/linux/proc_fs.h to the private header fs/proc/internal.h. The SPL relied on that to map Solaris' kstat to entries in /proc/spl/kstat. Since the proc_dir_entry structure is now private the only safe thing to do is wrap the opaque proc handle with our own structure. This actually ends up simplify the code and is good because it moves us away from depending on implementation details of /proc.

The Solaris Porting Layer (SPL) is a Linux kernel module which provides many of the Solaris kernel APIs. This shim layer makes it possible to run Solaris kernel code in the Linux kernel with relatively minimal modification. This can be particularly useful when you want to track upstream Solaris development closely and don’t want the overhead of maintaining a large patch which converts Solaris primitives to Linux primitives.
To build packages for your distribution:
$ ./configure
$ make pkg
To copy the kernel code inside your kernel source tree for builtin compilation:
$ ./configure --enable-linux-builtin --with-linux=/usr/src/linux-...
$ ./copy-builtin /usr/src/linux-...
Full documentation for building, configuring, and using the SPL can be found at: http://zfsonlinux.org
