OpenZFS 9580 - Add a hash-table on top of nvlist to speed-up operations = Motivation While dealing with another performance issue (see 126118f) we noticed that we spend a lot of time in various places in the kernel when constructing long nvlists. The problem is that when an nvlist is created with the NV_UNIQUE_NAME set (which is the case most of the time), we do a linear search through the whole list to ensure uniqueness for every entry we add. An example of the above scenario can be seen in the following flamegraph, where more than have the time of the zfsdev_ioctl() is spent on constructing nvlists. Flamegraph: https://sdimitro.github.io/img/flame/sdimitro_snap_unmount3.svg Adding a table to speed up lookups will help situations where we just construct an nvlist (like the scenario above), in addition to regular lookups and removals. = What this patch does In this diff we've implemented a hash-table on top of the nvlist code that converts most nvlist operations from O(# number of entries) to O(1)* (the start is for amortized time as the hash-table grows and shrinks depending on the # of entries - plain lookup is strictly O(1)). = Performance Analysis To analyze the performance improvement I just used the setup from the snapshot deletion issue mentioned above in the Motivation section. Basically I created 10K filesystems with one snapshot each and then I just used the API of libZFS_Core to pass down an nvlist of all the snapshots to have them deleted. The reason I used my own driver program was to have clean performance results of what actually happens in the kernel. The flamegraphs and wall clock times mentioned below were gathered from the start to the end of the driver program's run. Between trials the testpool used was completely destroyed, the system was rebooted and the testpool was completely recreated. The reason for this dance was to get consistent results. == Results (before patch): === Sampling Flamegraphs [Trial 1] https://sdimitro.github.io/img/flame/DLPX-53417/trial-A.svg [Trial 2] https://sdimitro.github.io/img/flame/DLPX-53417/trial-A2.svg [Trial 3] https://sdimitro.github.io/img/flame/DLPX-53417/trial-A3.svg === Wall clock times (in seconds) ``` [Trial 4] real 5.3 user 0.4 sys 2.3 [Trial 5] real 8.2 user 0.4 sys 2.4 [Trial 6] real 6.0 user 0.5 sys 2.3 ``` == Results (after patch): === Sampling Flamegraphs [Trial 1] https://sdimitro.github.io/img/flame/DLPX-53417/trial-Ae.svg [Trial 2] https://sdimitro.github.io/img/flame/DLPX-53417/trial-A2e.svg [Trial 3] https://sdimitro.github.io/img/flame/DLPX-53417/trial-A3e.svg === Wall clock times (in seconds) ``` [Trial 4] real 4.9 user 0.0 sys 0.9 [Trial 5] real 3.8 user 0.0 sys 0.9 [Trial 6] real 3.6 user 0.0 sys 0.9 ``` == Analysis The results between the trials are consistent so in this sections I will only talk about the flamegraph results from trial-1 and the wall-clock results from trial-4. From trial-1 we can see that zfs_dev_ioctl() goes from 2,331 to 996 samples counts. Specifically, the samples from fnvlist_add_nvlist() and spa_history_log_nvl() are almost gone (~500 & ~800 to 5 & 5 samples), leaving zfs_ioc_destroy_snaps() to dominate most samples from zfs_dev_ioctl(). From trial-4 we see that the user time dropped to 0 secods. I believe the consistent 0.4 seconds before my patch was applied was due to my driver program constructing the long nvlist of snapshots so it can pass it to the kernel. As for the system time, the effect there is more clear (2.3 down to 0.9 seconds). Porting Notes: * DATA_TYPE_DONTCARE case added to switch in fm_nvprintr() and zpool_do_events_nvprint().

Update build system and packaging Minimal changes required to integrate the SPL sources in to the ZFS repository build infrastructure and packaging. Build system and packaging: * Renamed SPL_* autoconf m4 macros to ZFS_*. * Removed redundant SPL_* autoconf m4 macros. * Updated the RPM spec files to remove SPL package dependency. * The zfs package obsoletes the spl package, and the zfs-kmod package obsoletes the spl-kmod package. * The zfs-kmod-devel* packages were updated to add compatibility symlinks under /usr/src/spl-x.y.z until all dependent packages can be updated. They will be removed in a future release. * Updated copy-builtin script for in-kernel builds. * Updated DKMS package to include the spl.ko. * Updated stale AUTHORS file to include all contributors. * Updated stale COPYRIGHT and included the SPL as an exception. * Renamed README.markdown to README.md * Renamed OPENSOLARIS.LICENSE to LICENSE. * Renamed DISCLAIMER to NOTICE. Required code changes: * Removed redundant HAVE_SPL macro. * Removed _BOOT from nvpairs since it doesn't apply for Linux. * Initial header cleanup (removal of empty headers, refactoring). * Remove SPL repository clone/build from zimport.sh. * Use of DEFINE_RATELIMIT_STATE and DEFINE_SPINLOCK removed due to build issues when forcing C99 compilation. * Replaced legacy ACCESS_ONCE with READ_ONCE. * Include needed headers for `current` and `EXPORT_SYMBOL`.

Register correct handlers in nvlist_alloc() The non-blocking allocation handlers in nvlist_alloc() would be mistakenly assigned if any flags other than KM_SLEEP were passed. This meant that nvlists allocated with KM_PUSHPUSH or other KM_* debug flags were effectively always using atomic allocations. While these failures were unlikely it could lead to assertions because KM_PUSHPAGE allocations in particular are guaranteed to succeed or block. They must never fail. Since the existing API does not allow us to pass allocation flags to the private allocators the cleanest thing to do is to add a KM_PUSHPAGE allocator.
