![]() In ext4_orphan_cleanup(), if ext4_truncate() failed to get a transaction handle, it didn't remove the inode from the in-core orphan list, which may probably trigger below error dump in ext4_destroy_inode() during the final iput() and could lead to memory corruption on the later orphan list changes. EXT4-fs (sda): Inode 6291467 (00000000b8247c67): orphan list check failed! 00000000b8247c67: 0001f30a 00000004 00000000 00000023 ............#... 00000000e24cde71: 00000006 014082a3 00000000 00000000 ......@......... 0000000072c6a5ee: 00000000 00000000 00000000 00000000 ................ ... This patch fix this by cleanup in-core orphan list manually if ext4_truncate() return error.

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.
