  "description": "In the Linux kernel, the following vulnerability has been resolved:  netfs: Fix folio_queue ENOMEM in writeback by adding a mempool  Fix the handling of folio_queue allocation failure in writeback by adding a mempool and passing in gfp_t flags to the rolling buffer functions that allocate memory, using the mempool if gfp != GFP_KERNEL.  This is then extended upwards and the gfp to be used for a request is stored in the netfs_io_request struct and is then used for both requests and subrequests, eliminating the sleeping loops there.  The failure caused:      folio != NULL     WARNING: fs/netfs/write_issue.c:603 at netfs_writepages\u002B0x883/0xa10 fs/netfs/write_issue.c:603, CPU#3: syz.0.17/5919",
