Subject: btrfs: Fix bool initialization/comparison
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=897ca8194cd1b287bc5e7d8a5edc2b9a041e15ba;p=openwrt%2Fstaging%2Fblogic.git

btrfs: Fix bool initialization/comparison

Bool initializations should use true and false. Bool tests don't need
comparisons.
