[PATCH 0/9] mm/damon: various fixes and cleanup of code, test, and docs

[SJ Park]

Fix and cleanup various parts of DAMON including its code, test, and
documentation.

Optimize the efficiency and monitoring accuracy of DAMON code with the
first five patches.  Remove unnecessary initializations in
damon_new_ctx() with patch 1 from Adrian Huang (Lenovo).  Align MMU
notifier ranges when clearing PTE/PMD young bits with patches 2 and 3
from Shubhang Kaushik (Ampere) and Aveline Noir.  Avoid DAMON_STAT idle
time percentile overflow on 32-bit architectures, and optimize out
unnecessary folio LRU isolation from DAMOS_MIGRATE action, with
patches 4 and 5 from Aveline Noir, respectively.

Fix and cleanup tests and documents with remaining four patches.  Let
sysfs.py test does not hang when it is executed under interactive
terminal with patch 6 from Jaeyeong Lee.  Fix typos, grammatical errors
and styles in DAMON_RECLAIM comments and DAMON_LRU_SORT user documents
with patches 7 and 8 from Manuel.  Finally, document how to disable
watermarks of DAMON_RECLAIM with patch 9 from Jinjie Ruan.
