Merge branch 'work.icache' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs inode freeing updates from Al Viro: "Introduction of separate method for RCU-delayed part of ->destroy_inode() (if any). Pretty much as posted, except that destroy_inode() stashes ->free_inode into the victim (anon-unioned with ->i_fops) before scheduling i_callback() and the last two patches (sockfs conversion and folding struct socket_wq into struct socket) are excluded - that pair should go through netdev once davem reopens his tree" * 'work.icache' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (58 commits) orangefs: make use of ->free_inode() shmem: make use of ->free_inode() hugetlb: make use of ->free_inode() overlayfs: make use of ->free_inode() jfs: switch to ->free_inode() fuse: switch to ->free_inode() ext4: make use of ->free_inode() ecryptfs: make use of ->free_inode() ceph: use ->free_inode() btrfs: use ->free_inode() afs: switch to use of ->free_inode() dax: make use of ->free_inode() ntfs: switch to ->free_inode() securityfs: switch to ->free_inode() apparmor: switch to ->free_inode() rpcpipe: switch to ->free_inode() bpf: switch to ->free_inode() mqueue: switch to ->free_inode() ufs: switch to ->free_inode() coda: switch to ->free_inode() ...
