Paulo Alcantara 18d86965e3 smb: client: fix rename(2) regression against samba ... After commit 2c7d399e55 ("smb: client: reuse file lease key in compound operations") the client started reusing lease keys for rename, unlink and set path size operations to prevent it from breaking its own leases and thus causing unnecessary lease breaks to same connection. The implementation relies on positive dentries and cifsInodeInfo::lease_granted to decide whether reusing lease keys for the compound requests. cifsInodeInfo::lease_granted was introduced by commit 0ab95c2510 ("Defer close only when lease is enabled.") to indicate whether lease caching is granted for a specific file, but that can only happen until file is open, so cifsInodeInfo::lease_granted was left uninitialised in ->alloc_inode and then client started sending random lease keys for files that hadn't any leases. This fixes the following test case against samba: mount.cifs //srv/share /mnt/1 -o ...,nosharesock mount.cifs //srv/share /mnt/2 -o ...,nosharesock touch /mnt/1/foo; tail -f /mnt/1/foo & pid=$! mv /mnt/2/foo /mnt/2/bar # fails with -EIO kill $pid Fixes: 0ab95c2510 ("Defer close only when lease is enabled.")
