Subject: gfs2: Use b_folio in gfs2_trans_add_meta()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=13a55c11b0a437190f7d2d8bb702a09071e59e56;p=users%2Fwilly%2Fpagecache.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.
