Subject: btrfs: make btrfs_page_mkwrite() to be subpage compatible
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2d8ec40ee46d211fa8396678210faf19e013b093;p=linux.git

btrfs: make btrfs_page_mkwrite() to be subpage compatible

Only set_page_dirty() and SetPageUptodate() is not subpage compatible.
Convert them to subpage helpers, so that __extent_writepage_io() can
submit page content correctly.
