From 273960b8f374b95ebd234a99607b7887f515c791 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Thu, 1 Feb 2024 12:41:42 -0800 Subject: bcachefs: time_stats: split stats-with-quantiles into a separate structure Currently, struct time_stats has the optional ability to quantize the information that it collects. This is /probably/ useful for callers who want to see quantized information, but it more than doubles the size of the structure from 224 bytes to 464. For users who don't care about that (e.g. upcoming xfs patches) and want to avoid wasting 240 bytes per counter, split the two into separate pieces. Signed-off-by: Darrick J.
