One other thing that I've noticed is that if you do: # mkfs.xfs -i align=0 /dev/foo that passes now, and it shouldn't. Prior to this patch, it said: Inodes always aligned for CRC enabled filesytems The above testcase actually alternates between pass & fail over the next several patches. If you have testcases for these conflicts, please try to make sure that they don't regress throughout the series. -Eric > Signed-off-by: Jan Tulak > --- > mkfs/xfs_mkfs.c | 152 ++++++++++++++++++++++++++------------------------------ > 1 file changed, 70 insertions(+), 82 deletions(-) > > diff --git a/mkfs/xfs_mkfs.c b/mkfs/xfs_mkfs.c > index 4ba6df05..c100fef9 100644 > --- a/mkfs/xfs_mkfs.c > +++ b/mkfs/xfs_mkfs.c > @@ -45,7 +45,7 @@ unsigned int sectorsize; > #define MAX_OPTS 16 > #define MAX_SUBOPTS 16 > #define SUBOPT_NEEDS_VAL (-1LL) > -#define MAX_CONFLICTS 8 > +#define MAX_CONFLICTS 32 > #define LAST_CONFLICT (-1) > > #define OPT_B 0 > @@ -409,7 +409,9 @@ struct opt_params { > }, > .subopt_params = { > { .index = I_ALIGN, > -
