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.
