Subject: [PATCH] smb: client: fix order of arguments of tracepoints
Date: Sat, 18 Jan 2025 21:03:30 +0100 [thread overview]
Message-ID: <20250118200330.21020-1-devosruben6@gmail.com> (raw)
The tracepoints based on smb3_inf_compound_*_class have tcon id and
session id swapped around. This results in incorrect output in
`trace-cmd report`.
Fix the order of arguments to resolve this issue. The trace-cmd output
below shows the before and after of the smb3_delete_enter and
smb3_delete_done events as an example. The smb3_cmd_* events show the
correct session and tcon id for reference.
Also fix tracepoint set -> get in the SMB2_OP_GET_REPARSE case.
