CIFS: add ONCE flag for cifs_dbg type
* Since cifs_vfs_error was just using pr_debug_ratelimited like the rest of cifs_dbg, move it there too * Add a ONCE type flag to call the pr_xxx_once() debug function instead of the ratelimited ones. To convert existing printk_once() calls to this we can run: perl -i -pE \ 's/printk_once\s*\(([^" \n]+)(.*)/cifs_dbg(VFS|ONCE,$2/g' \ fs/cifs/*.c Signed-off-by: Aurelien Aptel <aaptel@suse.com> Signed-off-by: Steve French <stfrench@microsoft.com>
