ok, sorry for the noise i did not know, for me that look unintended.

no need to cache, the idea was only to make the correlation between the name
and flags more obvious. (no need to hurry, i just noticed it)
if (strcmp(name, "acl") == 0) {
which = 0;
flags = YFS_ACL_WANT_ACL;
}
else if (strcmp(name, "acl_inherited") == 0) {
which = 1;
flags = 0;
}
else if (strcmp(name, "acl_num_cleaned") == 0) {
which = 2;
flags = 0;
}
else if (strcmp(name, "vol_acl") == 0) {
which = 3;
flags = YFS_ACL_WANT_VOL_ACL;
}
