+commit 0ac83722a09ccb15067cad91217103474b58dadf
+Author: Richard Yao <ryao@cs.stonybrook.edu>

+
+    Relicense zfs.gentoo.in from GPLv2 to 2-clause BSD
+    
+    As the Gentoo sys-fs/zfs maintainer, I receive license compatibility
+    questions and at times, those questions can be harassing. I feel that
+    the presence of the GPL in Gentoo's package metadata promotes such
+    questions.  zfs.gentoo.in is the only GPLv2 licensed file in ZFS, so I
+    have taken the liberty of contacting all contributors to this file to
+    request permission to relicense it.
+    
+    All of the contributors to this file have agreed to relicense it under
+    the 2-clause BSD license. I have added their Signed-offs to this commit,
+    in order of first contribution. Thankyou everyone for being so
+    understanding.

-    Make callers responsible for memory allocation in zfs_range_lock()
-    
-    zfs_range_lock() is used in zvols, and previously, it could deadlock due
-    to an allocation using KM_SLEEP. We avoid this by moving responsibility
-    the memory allocation from zfs_range_lock() to the caller. This enables
-    us to avoid such deadlocks and use stack allocations, which are more
-    efficient and prevents deadlocks. The contexts in which stack
-    allocations are done do not appear to be stack heavy, so we do not risk
-    overflowing the stack from doing this.
