File qemu-0.11-git-user-linux-fcntl_fixes_for_LTP.patch of Package qemu-svn (Revision 852e39ec4eedcd40eeadb54f6af3fb0b)

Currently displaying revision 852e39ec4eedcd40eeadb54f6af3fb0b, show latest

Fixes swaps on l_pid which were pretty much of random size. Implements
F_SETLEASE, F_GETLEASE. Now passes all LTP fcntl tests.
