Subject: f2fs: Add F2FS_F_SB()
X-Git-Tag: v6.14-rc1~63^2~26
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1cf746007005593aa51395302ca0d31814f4ce42;p=thirdparty%2Fkernel%2Flinux.git

f2fs: Add F2FS_F_SB()

This is the folio equivalent of F2FS_P_SB().  Removes a call to
page_file_mapping() as we know folios seen by f2fs are never part of
the swap cache.
