Description

In the Linux kernel, the following vulnerability has been resolved: nilfs2: replace WARN_ONs by nilfs_error for checkpoint acquisition failure If creation or finalization of a checkpoint fails due to anomalies in the checkpoint metadata on disk, a kernel warning is generated. This patch replaces the WARN_ONs by nilfs_error, so that a kernel, booted with panic_on_warn, does not panic. A nilfs_error is appropriate here to handle the abnormal filesystem condition. This also replaces the detected error codes with an I/O error so that neither of the internal error codes is returned to callers.
