2013-05-10 Thread Gabriel de Perthuis
9P optionally uses the FS_IOC_GETVERSION ioctl to get information about a file's version (sometimes called generation number). The code checks for supported filesystems at mount time, but some paths may come from other mounted filesystems. Change it to treat unsupported paths the same as
