Shift the asynchronous allocations over to use the taskq interfaces. This allows us to abandon the kernels delayed work queue interface and all the compatibility code it requires. This code never actually used the delay functionality it was just done this way to leverage the existing compatibility code. All that is required is a thread context to perform the allocation in. The only thing clever in this change is that we take advantage of the preallocated task queue entries to avoid a memory allocation. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov>
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
