Subject: f2fs: Pass a folio to nid_of_node()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=a63f2de2dd950aaa7c6008e90f30c43b34f643f5;p=users%2Fdwmw2%2Flinux.git

f2fs: Pass a folio to nid_of_node()

All callers have a folio so pass it in.  Also make the argument const
as the function does not modify it.
