Revision 2f33a706027c94cd4f70fcd3e3f4a17c1ce4ea4b authored by Hugh Dickins on 28 May 2020, 05:20:43 UTC, committed by Linus Torvalds on 28 May 2020, 18:35:40 UTC
When collapse_file() calls try_to_release_page(), it has already isolated
the page: so if releasing buffers happens to fail (as it sometimes does),
remember to putback_lru_page(): otherwise that page is left unreclaimable
and unfreeable, and the file extent uncollapsible.
