Subject: [PATCH v5 0/2] fix and improvement for file THP
Date: Tue, 5 Nov 2019 22:09:28 -0800	[thread overview]
Message-ID: <20191106060930.2571389-1-songliubraving@fb.com> (raw)

This set includes a fix and an improvement for file THP.

1/2 fixes pagecache corruption for file THP, where !PageUptodate page gets
collapsed into huge page. 1/2 is needed for 5.4.

2/2 improve collapse of file THP by flushing dirty page in collapse_file().
2/2 can wait until 5.5.

Thanks,
Song
