From 1b0e31861d98920c3823c7519ae762499811df00 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Tue, 11 Aug 2020 18:35:43 -0700 Subject: nilfs2: only call unlock_new_inode() if I_NEW Patch series "nilfs2 updates". This patch (of 3): unlock_new_inode() is only meant to be called after a new inode has already been inserted into the hash table. But nilfs_new_inode() can call it even before it has inserted the inode, triggering the WARNING in unlock_new_inode(). Fix this by only calling unlock_new_inode() if the inode has the I_NEW flag set, indicating that it's in the table.
