Subject: writeback: writeback_inodes_sb() should use bdi_start_writeback()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=56a131dcf7ed36c3c6e36bea448b674ea85ed5bb;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

writeback: writeback_inodes_sb() should use bdi_start_writeback()

Pointless to iterate other devices looking for a super, when
we have a bdi mapping.
