From: Nikolay Borisov Date: Thu, 8 Nov 2018 08:18:06 +0000 (+0200) Subject: btrfs: Move epd::extent_locked check to writepage_delalloc's caller X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7789a55aa1c98e3408a77167699f86fdb79f097b;p=openwrt%2Fstaging%2Fblogic.git btrfs: Move epd::extent_locked check to writepage_delalloc's caller If epd::extent_locked is set then writepage_delalloc terminates. Make this a bit more apparent in the caller by simply bubbling the check up. This enables to remove epd as an argument to writepage_delalloc in a future patch. No functional change.
