Subject: f2fs: fix to avoid unneeded unlock_new_inode
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d726732c7ce951da5468b577a89ac26ce3f5a860;p=linux.git

f2fs: fix to avoid unneeded unlock_new_inode

During ->lookup, I_NEW state of inode was been cleared in f2fs_iget,
so in error path, we don't need to clear it again.
