The following sequence triggers ubifs_assert(c, c->lst.taken_empty_lebs > 0); at the end of ubifs_remount_fs(): mount -t ubifs /dev/ubi0_0 /mnt echo 1 > /sys/kernel/debug/ubifs/ubi0_0/ro_error umount /mnt mount -t ubifs -o ro /dev/ubix_y /mnt mount -o remount,ro /mnt The resulting UBIFS assert failed in ubifs_remount_fs at 1878 (pid 161) is a false positive. In the case above c->lst.taken_empty_lebs has never been changed from its initial zero value. This will only happen when the deferred recovery is done. Fix this by doing the assertion only when recovery has been done already. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Richard Weinberger <richard@nod.at>
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.
