Subject: f2fs: switch init_inode_metadata() to passing parent and name separately
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=69f24eac55725859a89c440ee2d19f36fa09e8fc;p=linux-beck.git

f2fs: switch init_inode_metadata() to passing parent and name separately

... sure, it's tempting to just pass dentry.  Except that we don't
_have_ anything resembling a real dentry on one of the paths to it.
