The patch is doing
+ //if there is an existing lease, reuse it
+ if (dentry) {
+ inode = d_inode(dentry);
+ cinode = CIFS_I(inode);
+ if (cinode->lease_granted) {
+ oplock = SMB2_OPLOCK_LEVEL_LEASE;
+ memcpy(fid.lease_key, cinode->lease_key, SMB2_LEASE_KEY_SIZE);
+ }
+ }
and @inode ends up being the same for foo and bar from reproducer. So,
the client is trying to close bar file by using lease key from foo. The
server then fails to match @cinode->lease_key for bar file.
