commiteb1f822c76upstream. In commita44be64bbe("ext4: don't clear SB_RDONLY when remounting r/w until quota is re-enabled") we defer clearing tyhe SB_RDONLY flag in struct super. However, we didn't defer when we checked sb_rdonly() to determine the lazy itable init thread should be enabled, with the next result that the lazy inode table initialization would not be properly started. This can cause generic/231 to fail in ext4's nojournal mode. Fix this by moving when we decide to start or stop the lazy itable init thread to after we clear the SB_RDONLY flag when we are remounting the file system read/write.

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.
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.
