Re: [PATCH v14 022/138] mm/filemap: Add __folio_lock_or_retry()

Matthew Wilcox (Oracle) [off-list ref] wrote:

Convert __lock_page_or_retry() to __folio_lock_or_retry().  This actually
saves 4 bytes in the only caller of lock_page_or_retry() (due to better
register allocation) and saves the 14 byte cost of calling page_folio()
in __folio_lock_or_retry() for a total saving of 18 bytes.  Also use
a bool for the return type.
