When remounting ext4 from ro to rw, currently it allows its transition, even if ext4_commit_super() returns EIO. Even worse thing is, after that, fs/buffer complains buffer dirty bits like: Call trace: [<ffffff9750c259dc>] mark_buffer_dirty+0x184/0x1a4 [<ffffff9750cb398c>] __ext4_handle_dirty_super+0x4c/0xfc [<ffffff9750c7a9fc>] ext4_file_open+0x154/0x1c0 [<ffffff9750bea51c>] do_dentry_open+0x114/0x2d0 [<ffffff9750bea75c>] vfs_open+0x5c/0x94 [<ffffff9750bf879c>] path_openat+0x668/0xfe8 [<ffffff9750bf8088>] do_filp_open+0x74/0x120 [<ffffff9750beac98>] do_sys_open+0x148/0x254 [<ffffff9750beade0>] SyS_openat+0x10/0x18 [<ffffff9750a83ab0>] el0_svc_naked+0x24/0x28 EXT4-fs (dm-1): previous I/O error to superblock detected Buffer I/O error on dev dm-1, logical block 0, lost sync page write EXT4-fs (dm-1): re-mounted.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
