OpenZFS 2.0.4 Released With Linux 5.11 Support, Early Linux 5.12 Compatibility Updates
OpenZFS 2.0.4 brings official support for the Linux 5.11 kernel along with early compatibility bits for the in-development Linux 5.12. BIO changes needed to be accounted for in the OpenZFS code for making it build happy against Linux 5.12 Git at this still early stage while we'll see in the weeks ahead if any other changes for Linux 5.12 become warranted. OpenZFS 2.0.4 retains compatibility going back all the way to Linux 3.10 while on the BSD side remains focused on FreeBSD 12/13.
OpenZFS 2.0.4 also now properly initializes ZIL buffers, various FreeBSD specific fixes, support for using uClibc for compiling the test cases, and a variety of other generally small bug fixes.
