Merge patch series "two little writeback cleanups v2"

Christoph Hellwig <hch@lst.de> says:

This fixes one (of multiple) sparse warnings in fs-writeback.c, and
then reshuffles the code a bit that only the proper high level API
instead of low-level helpers is exported.

* patches from https://lore.kernel.org/r/20241112054403.1470586-1-hch@lst.de:
  writeback: wbc_attach_fdatawrite_inode out of line
  writeback: add a __releases annoation to wbc_attach_and_unlock_inode
