Subject: gfs2: Use b_folio in gfs2_trans_add_meta()
X-Git-Tag: v6.15-rc1~154^2~8
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3f2fc848be88470e585e41bb5379e4267e2ab720;p=thirdparty%2Fkernel%2Flinux.git

gfs2: Use b_folio in gfs2_trans_add_meta()

The lock bit is maintained on the folio, not on the page.  Saves two
calls to compound_head() as well as removing two references to
bh->b_page.
