Currently, ztest expects to get 3 and 4 as the file descriptors for data and random files, respectively. This is quite fragile and breaks easily if ztest is run with these file descriptors already opened (e.g. in a complex shell script). This patch fixes the issue by removing the assumptions on the file descriptor numbers that open() returns. For the random file (/dev/urandom), the new code doesn't rely on a shared file descriptor; instead, it reopens the file in the child. For the data file, the new code writes the file descriptor number into a "ZTEST_FD_DATA" environment variable so that it can be recovered after the execv() call.

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
