Subject: [XFS] If you mount an XFS filesystem with no mount options at all, then

[XFS] If you mount an XFS filesystem with no mount options at all, then
the "ikeep" option is set rather than "noikeep".

This regression was introduced in 970451.

With no mount options specified, xfs_parseargs() does the following:

int ikeep = 0;

args->flags |= XFSMNT_BARRIER;

args->flags2 |= XFSMNT2_COMPAT_IOSIZE;

if (!options)

goto done;

It only sets the above two options by default and before, it also used to
set XFSMNT_IDELETE by default.

If options are specified, then

if (!(args->flags & XFSMNT_DMAPI) && !ikeep)

args->flags |= XFSMNT_IDELETE;

is executed later on which is skipped by the "goto done;" above.

The solution is to invert the logic.
