When coding the pNFS server, I added vn_start_write() calls in nfsrv_copymr() done while the vnodes were locked, not realizing I had introduced LORs and possible deadlock when an exported file system on the MDS is suspended. This patch fixes the LORs by moving the vn_start_write() calls up to before where the vnodes are locked. For "tvp", the vn_start_write() probaby isn't necessary, because NFS mounts can't be suspended. However, I think doing so is harmless. Thanks go to kib@ for letting me know that I had introduced these LORs. This patch only affects the behaviour of the pNFS server when pnfsdscopymr(8) is used to recover a mirrored DS. |
