smb: client: no longer use smbdirect_socket_set_custom_workqueue()

2026-04-16T02:58:24Z

smbdirect.ko has global workqueues now, so we should use these default once. Cc: Steve French Cc: Tom Talpey Cc: Long Li Cc: Namjae Jeon Cc: linux-cifs@vger.kernel.org Cc: samba-technical@lists.samba.org Signed-off-by: Stefan Metzmacher Acked-by: Namjae Jeon Signed-off-by: Steve French

smb: client: make use of smbdirect.ko

2026-04-16T02:58:22Z

This means we no longer inline the common smbdirect .c files and use the exported functions from the module instead. Note the connection specific logging is still redirect to cifs.ko functions via smbdirect_socket_set_logging(). We still don't use real socket layer, but we're very close...

smb: client: only use public smbdirect functions

2026-04-16T02:58:22Z

Also remove a lot of unused includes... Cc: Steve French Cc: Tom Talpey Cc: Long Li Cc: Namjae Jeon Cc: linux-cifs@vger.kernel.org Cc: samba-technical@lists.samba.org Signed-off-by: Stefan Metzmacher Acked-by: Namjae Jeon Signed-off-by: Steve French

smb: client: make use of smbdirect_socket_create_kern()/smbdirect_socket_release()

2026-04-16T02:58:22Z

With this we no longer embed struct smbdirect_socket, which will allow us to make it private in the following commits.

smb: client: make use of smbdirect_socket_init_new() and smbdirect_connect_sync()

2026-04-16T02:58:22Z

This means we finally only use common functions in the client. We still use the embedded struct smbdirect_socket and are able to access internals, but the will be removed in the next commits as well.

smb: client: introduce and use smbd_debug_proc_show()

2026-04-16T02:58:22Z

This will allow us to make struct smbdirect_socket private in future. Cc: Steve French Cc: Tom Talpey Cc: Long Li Cc: Namjae Jeon Cc: linux-cifs@vger.kernel.org Cc: samba-technical@lists.samba.org Signed-off-by: Stefan Metzmacher Acked-by: Namjae Jeon Signed-off-by: Steve French

smb: client: introduce and use smbd_mr_fill_buffer_descriptor()

2026-04-16T02:58:22Z

This will allow us to make struct smbdirect_mr_io private in future. Cc: Steve French Cc: Tom Talpey Cc: Long Li Cc: Namjae Jeon Cc: linux-cifs@vger.kernel.org Cc: samba-technical@lists.samba.org Signed-off-by: Stefan Metzmacher Acked-by: Namjae Jeon Signed-off-by: Steve French

smb: client: make use of smbdirect_connection_send_{single_iter,immediate_work}()

2026-04-16T02:58:22Z

With this the low level send functions are in common, we'll have to do some more changes in generic smb code in order to use smbdirect_connection_send_iter() instead of looping around smbdirect_connection_send_single_iter(). David's cleanups will allow us to use smbdirect_connection_send_iter().

smb: client: let smbd_post_send_full_iter() get remaining_length and return data_length

2026-04-16T02:58:22Z

This will simplify further changes in order to share more common code in future. Cc: Steve French Cc: Tom Talpey Cc: Long Li Cc: Namjae Jeon Cc: linux-cifs@vger.kernel.org Cc: samba-technical@lists.samba.org Signed-off-by: Stefan Metzmacher Acked-by: Namjae Jeon Signed-off-by: Steve French
