[CIFS] redo existing session setup if needed in cifs_mount
When cifs_mount finds an existing SMB session that it can use for a new mount, it does not check to see whether that session is in need of being reconnected. An easy way to reproduce: 1) mount //server/share1 2) watch /proc/fs/cifs/DebugData for the share to go DISCONNECTED 3) mount //server/share2 with same creds as in step 1. The second mount will fail because CIFSTCon returned -EAGAIN. If you do an operation in share1 and then reattempt the mount it will work (since the session is reestablished). The following patch fixes this by having cifs_mount check the status of the session when it picks an existing session and calling cifs_setup_session on it again if it's in need of reconnection. Thanks to Wojciech Pilorz for the initial bug report. Signed-off-by: Jeff Layton <jlayton@tupile.poochiereds.net> Signed-off-by: Steve French <sfrench@us.ibm.com>
