And so:
/* 32 bit project quota always on */
/* attr2 always on */
if (projid16bit == 1) {
fprintf(stderr,
_("32 bit Project IDs always enabled on CRC enabled filesytems\n"));
usage();
}
That will prevent mkfs from making a CRC enabled filesystem.
And, realistically, what's the problem with enabling 32 bit project
IDs by default for all new filesystems in 3.2.0? I'm of the opinion
we should just leave the code as it is because all kernels since
2.6.37 support 32 bit projid and any kernel picking up
xfsprogs-3.2.0 when it is released will have a kernel that supports
it....
Cheers,
Dave.
