Subject: io_uring/zcrx: use folio_nr_pages() instead of shift operation
X-Git-Url: https://gentwo.org/gitweb/?a=commitdiff_plain;h=a0169c3a62875d1bafa0caffa42e1d1cf6aa40e6;p=linux%2F.git

io_uring/zcrx: use folio_nr_pages() instead of shift operation

folio_nr_pages() is a faster helper function to get the number of pages when
NR_PAGES_IN_LARGE_FOLIO is enabled.
