Brian Behlendorf 31f2b5abdf Remove TSD zfs_fsyncer_key 
It's my understanding that the zfs_fsyncer_key TSD was added as
a performance omtimization to reduce contention on the zl_lock
from zil_commit().  This issue manifested itself as very long
(100+ms) fsync() system call times for fsync() heavy workloads.

However, under Linux I'm not seeing the same contention that
was originally described.  Therefore, I'm removing this code
in order to ween ourselves off any dependence on TSD.  If the
original performance issue reappears on Linux we can revisit
fixing it without resorting to TSD.

This just leaves one small ZFS TSD consumer.  If it can be
cleanly removed from the code we'll be able to shed the SPL
TSD implementation entirely.

README.markdown

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
