Miquel Sabaté Solà 99e057f3d3 btrfs: fix NULL dereference on root when tracing inode eviction ... [ Upstream commit f157dd661339fc6f5f2b574fe2429c43bd309534 ] When evicting an inode the first thing we do is to setup tracing for it, which implies fetching the root's id. But in btrfs_evict_inode() the root might be NULL, as implied in the next check that we do in btrfs_evict_inode(). Hence, we either should set the ->root_objectid to 0 in case the root is NULL, or we move tracing setup after checking that the root is not NULL. Setting the rootid to 0 at least gives us the possibility to trace this call even in the case when the root is NULL, so that's the solution taken here.
