Subject: [PATCH 0/3] optimize writecache_writeback for performance
Date: Sun, 25 Aug 2019 15:24:30 +0800 [thread overview]
Message-ID: <20190825072433.2628-1-yehs2007@zoho.com> (raw)
From: Huaisheng Ye <yehs1@lenovo.com>
Patch 1 and 2 are used for cleaning the code, and they have got
Acked-by from Mikulas.
Patch 3 is used for performance optimization when writeback_all,
which could save more than half of time.
Of course, if the blocks in writecache are more uncontinuous and
disordered, the more performance improvement would be gained from
this patch.
Huaisheng Ye (3):
dm writecache: remove unused member pointer in writeback_struct
dm writecache: add unlikely for getting two block with same LBA
dm writecache: optimize performance by sorting the blocks for
writeback_all
