Browse Source 
Christoph Hellwig <hch@lst.de> says:

Two fixes for iomap_bio_read_folio_range_sync, a potential kernel
crash when tweaking the device integrity behvavior using sysfs,
and a missing bio_uninit that the Sashiko review of the first fix
found.

* patches from https://patch.msgid.link/20260804124404.737145-1-hch@lst.de:
  iomap: iomap_bio_read_folio_range_sync is missing a call to bio_uninit
  iomap: don't free integrity payload that doesn't exist
