Writeback is part of memory reclaimand must not fail due to ENOMEM, so it allocates under GFP_NOFSthrough mempool_alloc(), which may dip into the pool's reserve and,if that runs empty, wait for elements to be returned.  TheGFP_KERNEL paths, which can return -ENOMEM to their callers, invokethe pool's ->alloc() callback directly instead.\nThe direct call, however, skips the alloc_hooks() wrapper that themempool_alloc() macro provides.  The pool callbacks, mempool_alloc_slab()and mempool_kmalloc(), call kmem_cache_alloc_noprof() and kmalloc_noprof()and rely on current->alloc_tag having been set by the caller.  WithCONFIG_MEM_ALLOC_PROFILING_DEBUG=y this leads to\n    current->alloc_tag not set    WARNING: ./include/linux/alloc_tag.h:161 at __alloc_tagging_slab_alloc_hook    alloc_tag was not set    WARNING: ./include/linux/alloc_tag.h:166 at __alloc_tagging_slab_free_hook\nat allocation and free time respectively, as reported when readingfiles on a CIFS mount.  The allocations are also missing from/proc/allocinfo.\nWrap the direct ->alloc() invocations in alloc_hooks() with a newmempool_alloc_noreserve() helper in include/linux/mempool.h, next tothe other alloc_hooks()-wrapped macros such as mempool_alloc().  TheGFP_KERNEL paths keep their failable allocation semantics, they justget tagged
