A remount with a new echo_interval value silently\nhas no effect on the echo keepalive timer.\n\nAdd echo_interval to smb3_sync_server_opts() under srv_lock so the\nnew interval is pushed to the live server struct. Reschedule the echo\ndelayed work via mod_delayed_work() so the new interval takes effect\nimmediately rather than after the current timer fires.\n\nSigned-off-by: Rajasi Mandal \n---\n fs/smb/client/fs_context.c | 12 +++++++++---\n 1 file changed, 9 insertions(+), 3 deletions(-)","diff":"diff --git a/fs/smb/client/fs_context.c b/fs/smb/client/fs_context.c\nindex fd1060483bf2..45173f287f00 100644\n--- a/fs/smb/client/fs_context.c\n+++ b/fs/smb/client/fs_context.c\n@@ -1329,9 +1329,9 @@ static void smb3_sync_tcon_opts(struct cifs_sb_info *cifs_sb,\n \n /*\n * Synchronize server-level options that are stored on TCP_Server_Info\n- * at mount time.
