Aconcurrent buffered write via netfs_perform_write() -- which onlyneeds i_rwsem shared -- could dirty new pages after the flush butbefore the local truncation, and those pages would be silentlydiscarded by cifs_setsize() -> truncate_pagecache().\nFix by acquiring inode_lock (exclusive i_rwsem) andfilemap_invalidate_lock at the top of cifs_do_truncate(), so theentire flush-truncate-resize sequence is atomic with respect to:\n  - buffered writes (blocked by exclusive i_rwsem, since    netfs_start_io_write takes i_rwsem shared),  - read page faults (blocked by exclusive invalidate_lock, since    filemap_fault takes it shared),  - writeback collection (blocked by netfs_wb_begin/netfs_wb_end    around the server truncate and local resize, since    netfs_writepages also acquires the wb lock).\nhttps://www.cve.org/CVERecord?id=CVE-2026-99111https://git.kernel.org/stable/c/4d143608a0445443a85c9b29f4c9f8e63d5dbfc9https://git.kernel.org/stable/c/ffa66fdc7d35b890606767c4d2c7ac26b4d90a99https://git.kernel.org/stable/c/a8603b52b39f520ea8a34def74c23fba87396d3e#kernel
