Subject: f2fs: return bool from __f2fs_write_meta_folio
X-Git-Tag: v6.16-rc1~115^2~18
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=39122e454419e31c2a20ac171687ab2e44a407ba;p=linux-block.git

f2fs: return bool from __f2fs_write_meta_folio

__f2fs_write_meta_folio can only return 0 or AOP_WRITEPAGE_ACTIVATE.
As part of phasing out AOP_WRITEPAGE_ACTIVATE, switch to a bool return
instead.
