2020-09-25xfs: remove deprecated sysctl optionsPavel Reichl
These optionr were for Irix compatibility, probably for clustered XFS clients in a heterogenous cluster which contained both Irix & Linux machines, so that behavior would be consistent. That doesn't exist anymore and it's no longer needed. Signed-off-by: Pavel Reichl <preichl@redhat.com> Reviewed-by: Darrick J.

2020-09-25xfs: remove deprecated mount optionsPavel Reichl
ikeep/noikeep was a workaround for old DMAPI code which is no longer relevant. attr2/noattr2 - is for controlling upgrade behaviour from fixed attribute fork sizes in the inode (attr1) and dynamic attribute fork sizes (attr2). mkfs has defaulted to setting attr2 since 2007, hence just about every XFS filesystem out there in production right now uses attr2.

2020-09-15xfs: deprecate the V4 formatDarrick J. Wong
The V4 filesystem format contains known weaknesses in the on-disk format that make metadata verification diffiult. In addition, the format does not support dates past 2038 and will not be upgraded to do so. We should start the process of retiring the old format to close off attack surfaces and to encourage users to migrate onto V5. Therefore, make XFS V4 support a configurable option. For the first period it will be default Y in case some distributors want to withdraw support early; for the second period it will be default N so that anyone who wishes to continue support can do so; and after that, support will be removed from the kernel. Dates for these events have been added to the upstream kernel. Signed-off-by: Darrick J.
