Meetakshi Setiya 1e60bc0e95 smb: client: retry compound request without reusing lease ... [ Upstream commit 71f15c90e7 ] There is a shortcoming in the current implementation of the file lease mechanism exposed when the lease keys were attempted to be reused for unlink, rename and set_path_size operations for a client. As per MS-SMB2, lease keys are associated with the file name. Linux smb client maintains lease keys with the inode. If the file has any hardlinks, it is possible that the lease for a file be wrongly reused for an operation on the hardlink or vice versa. In these cases, the mentioned compound operations fail with STATUS_INVALID_PARAMETER. This patch adds a fallback to the old mechanism of not sending any lease with these compound operations if the request with lease key fails with STATUS_INVALID_PARAMETER. Resending the same request without lease key should not hurt any functionality, but might impact performance especially in cases where the error is not because of the usage of wrong lease key and we might end up doing an extra roundtrip.
