Previously,\nchanging this option via remount was silently accepted but had no effect\nbecause the value was never synced from the updated ctx to the live tcon.\n\nAdd no_lease to smb3_sync_tcon_opts() so the flag is propagated to all\ntcons on remount, matching the pattern used by retry, nodelete, and\nmax_cached_dirs.\n\nWhen switching to nolease, also close all deferred file handles via\ncifs_close_all_deferred_files(). Deferred handles retain their\noriginal lease from the previous open; without closing them, a\nsubsequent open would reuse the cached handle and inherit the stale\nlease, preventing nolease from taking effect.\n\nBoth transitions are safe:\n - lease -> nolease: deferred handles are force-closed, and future\n opens get OPLOCK_LEVEL_NONE.\n - nolease -> lease: future opens will request leases; existing\n uncached files remain uncached until reopened.\n\nOn reconnect, cifs_reopen_file() reads the current tcon->no_lease and\nthe server grants (or not) accordingly, so the per-inode cache state\nis naturally updated.\n\nSigned-off-by: Rajasi Mandal <rajasimandal@microsoft.com>\n---\n fs/smb/client/fs_context.c | 4 ++++\n 1 file changed, 4 insertions(+)", "diff": "diff --git a/fs/smb/client/fs_context.c b/fs/smb/client/fs_context.c\nindex 5f0637035172..ce4842e778c4 100644\n--- a/fs/smb/client/fs_context.c\n+++ b/fs/smb/client/fs_context.c\n@@ -1330,8 +1330,12 @@ static void smb3_sync_tcon_opts(struct cifs_sb_info *cifs_sb,\n \n \t\tspin_lock(&tcon->tc_lock);\n \t\ttcon->retry = ctx->retry;\n+\t\ttcon->no_lease = ctx->no_lease;\n \t\ttcon->max_cached_dirs = ctx->max_cached_dirs;\n \t\tspin_unlock(&tcon->tc_lock);\n+\n+\t\tif (ctx->no_lease)\n+\t\t\tcifs_close_all_deferred_files(tcon);\n \t}\n \tspin_unlock(&cifs_sb->tlink_tree_lock);\n }\n", "prefixes": [ "6/9" ] }
