LOLi 7522a26077 Add limits to spa_slop_shift tunable ... This change adds limits to the possible spa_slop_shift values set via the sysfs interface. Accepted values are from a minimum of 1 to a maximum of 31 (inclusive): these limits are based on the following values observed on a 128PB file-vdev test pool: spa_slop_shift=1, spa_get_slop_space=63.5PiB spa_slop_shift=2, spa_get_slop_space=31.8PiB spa_slop_shift=3, spa_get_slop_space=15.9PiB spa_slop_shift=4, spa_get_slop_space=7.9PiB spa_slop_shift=5, spa_get_slop_space=4PiB spa_slop_shift=6, spa_get_slop_space=2PiB ... spa_slop_shift=25, spa_get_slop_space=4GiB spa_slop_shift=26, spa_get_slop_space=2GiB spa_slop_shift=27, spa_get_slop_space=1016MiB spa_slop_shift=28, spa_get_slop_space=508MiB spa_slop_shift=29, spa_get_slop_space=254MiB spa_slop_shift=30, spa_get_slop_space=128MiB spa_slop_shift=31, spa_get_slop_space=128MiB spa_slop_shift=32, spa_get_slop_space=128MiB Reviewed-by: Richard Elling <Richard.Elling@RichardElling.com> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: loli10K <ezomori.nozomu@gmail.com> Closes #7876 Closes #7900		2018-09-20 21:10:12 -07:00
