Subject: btrfs: Fix wrong btrfs_delalloc_release_extents parameter
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=336a8bb8e36a273a802a54b2e673c777c9c62fb1;p=openwrt%2Fstaging%2Fblogic.git

btrfs: Fix wrong btrfs_delalloc_release_extents parameter

Commit 43b18595d660 ("btrfs: qgroup: Use separate meta reservation type
for delalloc") merged into mainline is not the latest version submitted
to mail list in Dec 2017.

It has a fatal wrong @qgroup_free parameter, which results increasing
qgroup metadata pertrans reserved space, and causing a lot of early EDQUOT.

Fix it by applying the correct diff on top of current branch.
