Pull vfs iomap updates from Christian Brauner:

 - Erofs page cache sharing preliminaries:

   Plumb a void *private parameter through iomap_read_folio() and
   iomap_readahead() into iomap_iter->private, matching iomap DIO. Erofs
   uses this to replace a bogus kmap_to_page() call, as preparatory work
   for page cache sharing.

 - Fix for invalid folio access:

   Fix an invalid folio access when a folio without iomap_folio_state
   is fully submitted to the IO helper — the helper may call
   folio_end_read() at any time, so ctx->cur_folio must be invalidated
   after full submission.

* tag 'vfs-7.0-rc1.iomap' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
  iomap: fix invalid folio access after folio_end_read()
  erofs: hold read context in iomap_iter if needed
  iomap: stash iomap read ctx in the private field of iomap_iter
