Revision 9dfb3b8d655022760ca68af11821f1c63aa547c3 authored by Matthew Wilcox (Oracle) on 30 July 2022, 04:25:18 UTC, committed by Andrew Morton on 28 August 2022, 21:02:43 UTC
If we allocate a new page, we need to make sure that our folio matches that new page. If we do end up in this code path, we store the wrong page in the shmem inode's page cache, and I would rather imagine that data corruption ensues. This will be solved by changing shmem_replace_page() to shmem_replace_folio(), but this is the minimal fix.
