From 785bc568161d96fdbd4326294d427a48e66fe60f Mon Sep 17 00:00:00 2001 From: Namjae Jeon Date: Mon, 27 Apr 2026 22:58:52 +0900 Subject: [PATCH] ntfs: fix error handling in ntfs_write_iomap_end_resident() When ntfs_attr_get_search_ctx() fails and returns NULL, the function returned early without calling put_page(ipage). Fix this by jumping to err_out label on error. The err_out path now properly releases the page and the mutex, with a NULL check for the search context.
