Linux kernel source tree
005c5db8fd
The inline directory verifiers should be called on the inode fork data, which means after iformat_local on the read side, and prior to ifork_flush on the write side. This makes the fork verifier more consistent with the way buffer verifiers work -- i.e. they will operate on the memory buffer that the code will be reading and writing directly. Furthermore, revise the verifier function to return -EFSCORRUPTED so that we don't flood the logs with corruption messages and assert notices. This has been a particular problem with xfs/348, which triggers the XFS_WANT_CORRUPTED_RETURN assertions, which halts the kernel when CONFIG_XFS_DEBUG=y. Disk corruption isn't supposed to do that, at least not in a verifier. Reviewed-by: Brian Foster <bfoster@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Darrick J.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
