Subject: [PATCH v3 0/6] Generic per-sb io stats
Date: Tue, 1 Mar 2022 20:42:15 +0200 [thread overview]
Message-ID: <20220301184221.371853-1-amir73il@gmail.com> (raw)
Miklos,
Following your feedback on v2 [1], I moved the iostats to per-sb.
Thanks,
Amir.

Changes since v2:
- Change from per-mount to per-sb io stats (szeredi)
- Avoid percpu loop when reading mountstats (dchinner)
Changes since v1:
- Opt-in for per-mount io stats for overlayfs and fuse
Amir Goldstein (6):
lib/percpu_counter: add helpers for arrays of counters
fs: add optional iostats counters to struct super_block
fs: collect per-sb io stats
fs: report per-sb io stats
ovl: opt-in for per-sb io stats
fuse: opt-in for per-sb io stats
