On Feb. 28, a problem was reported on freebsd-stable@ where a nfsd thread processing an ExchangeID operation was blocked for a long time by another nfsd thread performing a copy_file_range. This occurred because the copy_file_range was taking a long time, but also because handling a clientID requires that all other nfsd threads be blocked via an exclusive lock, as required by ExchangeID. This patch adds two arguments to nfsv4_cleanclient() so that it can optionally be called with a mutex held. For this patch, the first of these arguments is "false" and, as such, there is no change in semantics. However, this change will allow a future commit to modify handling of the clientID so that it can be done with a mutex held while other nfsd threads continue to process NFS RPCs. MFC after: 1 month |
