From afe6f65353b644f55875d42d812ffe87f1887d68 Mon Sep 17 00:00:00 2001 From: Ronnie Sahlberg Date: Wed, 28 Aug 2019 17:15:35 +1000 Subject: cifs: add new debugging macro cifs_server_dbg which can be used from contexts where we have a TCP_Server_Info *server. This new macro will prepend the debugging string with "Server: " which will help when debugging issues on hosts with many cifs connections to several different servers. Convert a bunch of cifs_dbg(VFS) calls to cifs_server_dbg(VFS) Signed-off-by: Ronnie Sahlberg Signed-off-by: Steve French --- fs/cifs/cifs_debug.h | 31 +++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) (limited to 'fs/cifs/cifs_debug.h') diff --git a/fs/cifs/cifs_debug.h b/fs/cifs/cifs_debug.h index 3d392620a2f4..567af916f103 100644 --- a/fs/cifs/cifs_debug.h +++ b/fs/cifs/cifs_debug.h @@ -80,6 +80,30 @@ do { \ type, fmt, ##__VA_ARGS__); \ } while (0) +#define cifs_server_dbg_func(ratefunc, type, fmt, ...) \ +do { \ + if ((type) & FYI && cifsFYI & CIFS_INFO) { \ + pr_debug_ ## ratefunc("%s: Server:%s " fmt, \ + __FILE__, server->hostname, ##__VA_ARGS__);\ + } else if ((type) & VFS) { \ + pr_err_ ## ratefunc("CIFS VFS: Server:%s " fmt, \ + server->hostname, ##__VA_ARGS__); \ + } else if ((type) & NOISY && (NOISY != 0)) { \ + pr_debug_ ## ratefunc("Server:%s " fmt, \ + server->hostname, ##__VA_ARGS__); \ + } \ +} while (0) + +#define cifs_server_dbg(type, fmt, ...) \ +do { \ + if ((type) & ONCE) \ + cifs_server_dbg_func(once, \ + type, fmt, ##__VA_ARGS__); \ + else \ + cifs_server_dbg_func(ratelimited, \ + type, fmt, ##__VA_ARGS__); \ +} while (0) + /* * debug OFF * --------- @@ -91,6 +115,13 @@ do { \ pr_debug(fmt, ##__VA_ARGS__); \ } while (0) +#define cifs_server_dbg(type, fmt, ...) \ +do { \ + if (0) \ + pr_debug("Server:%s " fmt, \ + server->hostname, ##__VA_ARGS__); \ +} while (0) + #define cifs_info(fmt, ...) \ do { \ pr_info("CIFS: "fmt, ##__VA_ARGS__); \ -- cgit v1.2.3
