When an FS crashes, VFS will clean up resources tied to that FS: - Pending requests to the FS are canceled (i.e., fail with EIO) - Threads waiting for a reply are stopped (i.e., fail with EIO) - Open files are marked invalid. Future operations on a file descriptor will cause EBADF errors. - vmnt entry is cleared, so in-flight system calls that got past the file descriptor check but not yet talking to the crashed FS, will fail with EIO. - The reference counter of the mount point is decreased, effectively removing the crashed FS from the file system tree. Descendants of this part of the tree are unreachable by means of a path, but can still be unmounted by feeding the block special file to unmount(2). This patch also gets rid of the "not a known driver endpoint" messages during shutdown. |
