This is notable because this commit refactors the code, adding a new KM_SLEEP allocation. It is not clear to me whether this should be converted to KM_PUSHPAGE. 3. We had a merge conflict in libzfs_sendrecv.c because of copyright notices. 4. Several small C99 compatibility fixed were made.	2013-11-04 11:17:48 -08:00
