Merge tag 'pull-file_inode' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull file_inode() updates from Al Vrio: "whack-a-mole: cropped up open-coded file_inode() uses..." * tag 'pull-file_inode' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: orangefs: use ->f_mapping _nfs42_proc_copy(): use ->f_mapping instead of file_inode()->i_mapping dma_buf: no need to bother with file_inode()->i_mapping nfs_finish_open(): don't open-code file_inode() bprm_fill_uid(): don't open-code file_inode() sgx: use ->f_mapping... exfat_iterate(): don't open-code file_inode(file) ibmvmc: don't open-code file_inode()
