[PATCH v2 10/21] fs: introduce alloc_inode_sb() to allocate filesystems specific inode

From: Muchun Song
Date: Thu May 27 2021 - 02:25:58 EST

The allocated inode cache will be added to its memcg list_lru, we should
allocate its list_lru_one structure in advance. Introduce alloc_inode_sb
which is used for allocating filesystems specific inodes to set up the
inode reclaim context correctly.
