Increasing this limit costs us 6144 bytes of memory per mounted filesystem, but this is small price to pay for accomplishing the following: * Allows for up to 256-way concurreny when performing lookups which helps performance when there are a large number of processes. * Minimizes the likelyhood of encountering the deadlock described in issue #1101. Because vmalloc() won't strictly honor __GFP_FS there is still a very remote chance of a deadlock. See the zfsonlinux/spl@043f9b57 commit.

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
