zfs_arc_overflow_shift was never a parameter:ca0bf58d65("Illumos 5497 - lock contention on arcs_mtx") is the only result in git log -Soverflow_shift, and it wasn't exposed then, nor is it now zfs_read_chunk_size was renamed to zfs_vnops_read_chunk_size ine53d678d4a("Share zfs_fsync, zfs_read, zfs_write, et al between Linux and FreeBSD") zio_decompress_fail_fraction was never a parameter: it was added inc3bd3fb4ac("OpenZFS 9403 - assertion failed in arc_buf_destroy()") as a developer aid for setting in zdb, but it's a dangerous test tunable and has no place in public documentation, (not to mention that it obviously doesn't work): > Although this did uncover a few low priority issues, this unfortuantely also causes ztest to ASSERT in many locations where the code is working correctly since it is designed to fail on IO errors. Developers can manually set this variable with the '-o' option to find and debug issues.
