ext4_mark_inode_dirty() can fail for real reasons. Ignoring its return value may lead ext4 to ignore real failures that would result in corruption / crashes. Harden ext4_mark_inode_dirty error paths to fail as soon as possible and return errors to the caller whenever appropriate. One of the possible scnearios when this bug could affected is that while creating a new inode, its directory entry gets added successfully but while writing the inode itself mark_inode_dirty returns error which is ignored. This would result in inconsistency that the directory entry points to a non-existent inode. Ran gce-xfstests smoke tests and verified that there were no regressions.

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.
