Oh, if I'd read the context... ;)
>>> echo "1 above xfs acl max"
and:
XFS_ACL_MAX_ENTRIES=25
num_aces_pre=`expr $XFS_ACL_MAX_ENTRIES - 1`
num_aces_post=`expr $XFS_ACL_MAX_ENTRIES + 1`
acl1=`_create_n_aces $num_aces_pre`
acl2=`_create_n_aces $XFS_ACL_MAX_ENTRIES`
acl3=`_create_n_aces $num_aces_post`
Sorry for not reading more.
interesting that it's a udf test too...
Ok, but right - it's testing an xfs specific limit.
Your new test can probably be generic, with a _require_acls
to skip the test on any fs w/o acl support.
