From 15e7b6d753b815b19b375dcd4593534c0f157c66 Mon Sep 17 00:00:00 2001 From: Steve French Date: Sat, 26 Mar 2022 12:47:57 -0500 Subject: smb3: move defines for ioctl protocol header and SMB2 sizes to smbfs_common The definitions for the ioctl SMB3 request and response as well as length of various fields defined in the protocol documentation were duplicated in fs/ksmbd and fs/cifs. Move these to the common code in fs/smbfs_common/smb2pdu.h Reviewed-by: Namjae Jeon Signed-off-by: Steve French --- fs/cifs/cifsglob.h | 6 ------ fs/cifs/cifspdu.h | 12 ------------ fs/cifs/smb2glob.h | 11 ----------- fs/cifs/smb2pdu.h | 41 ----------------------------------------- 4 files changed, 70 deletions(-) (limited to 'fs/cifs') diff --git a/fs/cifs/cifsglob.h b/fs/cifs/cifsglob.h index 48b343d03430..ad3cd6053f4e 100644 --- a/fs/cifs/cifsglob.h +++ b/fs/cifs/cifsglob.h @@ -852,13 +852,7 @@ compare_mid(__u16 mid, const struct smb_hdr *smb) #define CIFS_MAX_RFC1002_WSIZE ((1<<17) - 1 - sizeof(WRITE_REQ) + 4) #define CIFS_MAX_RFC1002_RSIZE ((1<<17) - 1 - sizeof(READ_RSP) + 4) -/* - * The default wsize is 1M. find_get_pages seems to return a maximum of 256 - * pages in a single call.
