Hi,

I'd like to know if it is possible in a simple & safe way to increase the number of supported ACLs on an already existing FS.

xfs_acl.h:
#define XFS_ACL_MAX_ENTRIES 25

Changing XFS_ACL_MAX_ENTRIES to something higher should do the trick, but will it be safe: ie: will I risk corrupting the FS this way ?

I understand it'll imply a performance penalty if I add too many ACLs.

Thanks
