This reverts commitb00131d43cwhich is no longer needed due toe89260a1c8. This change forces all xattr znodes to hold a reference on their parent which ensures prune_icache() will never attempt to evict both the parent and child concurrently. This effectively prevents the deadlock condition from ever occuring. Therefore we can safely revert back to the upstream synchronous cleanup code. This is nice because it keeps our code base closer to upstream and resolves the performance issues introduced by the original deadlock fix.

Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!
$ ./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 ZFS can be found at: http://zfsonlinux.org
