I too would be really interested in any real-world application for which the cost of the stat() was any kind of major performance hit. > p.s. not having looked at the code, > the atomic ops seems unusual in the > presence of the static last_... variables. We are implicitly relying on aligned word size assignment atomicity here it looks like, yes. I haven't looked if there are other places in glibc doing this or if there's some infrastructure for it. To be clear this patch is derived from the OpenSUSE one; I didn't change the semantics there. -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel
