X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=12ecbb4b1d765a5076920999298d9625439dbe58;p=openwrt%2Fstaging%2Fblogic.git

ufs: Fix warning from unlock_new_inode()

Commit e4502c63f56aeca88 (ufs: deal with nfsd/iget races) introduced
unlock_new_inode() call into ufs_add_nondir(). However that function
gets called also from ufs_link() which hands it already initialized
inode and thus unlock_new_inode() complains. The problem is harmless but
annoying.

Fix the problem by opencoding necessary stuff in ufs_link()
