When that happens, the call\nto put_nfs_open_context() can trigger a synchronous delegreturn call\nwhich deadlocks because it is not marked as privileged.\n\nInstead, ensure that the call to nfs4_inode_return_delegation_on_close()\ncatches the delegreturn, and schedules it asynchronously.\n\ud83d\udccf Published: 2025-04-01T15:26:51.290Z\n\ud83d\udccf Modified: 2025-04-01T15:26:51.290Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/4fe4ae6c2e01d028856b73b6328b12b8945df871\n2. https://git.kernel.org/stable/c/f41a60bc43e7abbc636fee78bed0d74c31e738b0\n3. https://git.kernel.org/stable/c/8f8df955f078e1a023ee55161935000a67651f38", "creation_timestamp": "2025-04-01T15:32:38.000000Z"} 2025-04-01T15:32:38+00:00
