Although remount already stored\nthe new value in cifs_sb->ctx, it was never propagated to\nserver->retrans, so the running connection kept using the old count.\n\nIntroduce smb3_sync_server_opts() to push ctx options that live on\nTCP_Server_Info into the live server struct after a successful\nremount.  For now it handles retrans; subsequent patches will extend\nit to other server-level knobs.\n\nThe assignment is guarded (if ctx->retrans) so that a bare\n'mount -o remount' (which re-parses /proc/mounts and gets\nretrans=0 because cifs_show_options does not print it) does not\naccidentally reset the value to zero.\n\nSigned-off-by: Rajasi Mandal <rajasimandal@microsoft.com>\n---\n fs/smb/client/fs_context.c | 17 +++++++++++++++++\n 1 file changed, 17 insertions(+)",
