From 0e8868212d1ca2f639171feb93f7b2b270ec9aba Mon Sep 17 00:00:00 2001 From: Steve French Date: Mon, 19 Apr 2021 23:22:37 -0500 Subject: [PATCH] smb3: limit noisy error For servers which don't support copy_range (SMB3 CopyChunk), the logging of: CIFS: VFS: \\server\share refcpy ioctl error -95 getting resume key can fill the client logs and make debugging real problems more difficult. Change the -EOPNOTSUPP on copy_range to a "warn once" Signed-off-by: Steve French --- fs/cifs/smb2ops.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/fs/cifs/smb2ops.c b/fs/cifs/smb2ops.c index 5ccc36d98dad..dd0eb665b680 100644 --- a/fs/cifs/smb2ops.c +++ b/fs/cifs/smb2ops.c @@ -1567,7 +1567,10 @@ SMB2_request_res_key(const unsigned int xid, struct cifs_tcon *tcon, NULL, 0 /* no input */, CIFSMaxBufSize, (char **)&res_key, &ret_data_len); - if (rc) { + if (rc == -EOPNOTSUPP) { + pr_warn_once("Server share %s does not support copy range\n", tcon->treeName); + goto req_res_key_exit; + } else if (rc) { cifs_tcon_dbg(VFS, "refcpy ioctl error %d getting resume key\n", rc); goto req_res_key_exit; } -- 2.27.0
