Subject: linux-next: build failure after merge of the fuse tree

---

Hi all,

After merging the fuse tree, today's linux-next build (x86_64
allmodconfig) failed like this:

ERROR: modpost: ".delete_from_page_cache" [fs/fuse/fuse.ko] undefined!

Caused by commit

0d659ac83481 ("fuse: fix readdir cache race")

delete_from_page_cache has not been exported to modules since commit

452e9e6992fe ("filemap: Add filemap_remove_folio and __filemap_remove_folio")

Which was merged into Linus tree in v5.17-rc1.

I have used the fuse tree from next-20221012 for today.

Is this really destined for v6.1?

This particular patch, yes. I posted the patch and asked Willy about
delete_from_page_cache().

Rebased my for-next branch on HEAD and re-added the EXPORT_SYMBOL to
fix this for now.

Thanks,
