Subject: ext4: remove unnecessary ext4_get_group_info in ext4_mb_load_buddy
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=529da704ad1ead755d9e40721f29446cb278e099;p=openwrt%2Fstaging%2Fblogic.git

ext4: remove unnecessary ext4_get_group_info in ext4_mb_load_buddy

ext4_mb_load_buddy() calls ext4_get_group_info() for setting both
"grp" and "e4b->bd_info", but it could do "e4b->bd_info = grp".
