[PATCH v1 2/3] fuse: use GFP_KERNEL_ACCOUNT for allocations in fuse_dev_alloc

From: Alexander Mikhalitsyn
Date: Fri Jan 05 2024 - 10:22:38 EST


fuse_dev_alloc() is called from the process context and it makes
sense to properly account allocated memory to the kmemcg as these
allocations are for long living objects.
