There's more to it than just that, actually. Renaming an entire subtree won't update the parent attribute of files in there, so they will appear to be incorrect (*). This patch introduces a mechanism that could be used to force them to be updated. (*) I'm well aware that they contain enough information to find the updated information, so the redundant info in this attribute can be harmlessly out-of-date, but if someone plans to use the data for other purposes (like I sometimes do), it's useful to have them fully up to date. I also move large trees around, which makes this issue visible. -- Alexandre Oliva, freedom fighter http://FSFLA.org/~lxoliva/ You must be the change you wish to see in the world. -- Gandhi Be Free! -- http://FSFLA.org/ FSF Latin America board member Free Software Evangelist Red Hat Brazil Compiler Engineer -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
