Greg, Please consider adding the following XFS patches on linux-4.14.y branch to fix NULL pointer dereference errors in lookup_slow() on a NULL inode->i_ops and for a corrupted xfs image after xfs_da_shrink_inode(): ee457001ed6c ("xfs: catch inode allocation state mismatch corruption") afca6c5b2595 ("xfs: validate cached inodes are free when allocated") bb3d48dcf86a ("xfs: don't call xfs_da_shrink_inode with NULL bp") Thanks. -- All the best, Eduardo Valentin
