Re: [PATCH] btrfs: remove verity Merkle folio from page cache on error

[Yichong Chen]

Hi,

Thanks for the report.

This was a problem in v1.  The patch called filemap_remove_folio(), which is
not exported and therefore breaks when btrfs is built as a module.

I avoided filemap_remove_folio() in v2, and the patch has since been reworked
further.  The latest version no longer calls filemap_remove_folio():

  [PATCH v4] btrfs: retry verity reads for not-uptodate Merkle folios

Thanks,
Yichong
