    ext4: force inode writes when nfsd calls commit_metadata() · fde87268
    Theodore Ts'o authored
    Some time back, nfsd switched from calling vfs_fsync() to using a new
    commit_metadata() hook in export_operations().  If the file system did
    not provide a commit_metadata() hook, it fell back to using
    sync_inode_metadata().  Unfortunately doesn't work on all file
    systems.  In particular, it doesn't work on ext4 due to how the inode
    gets journalled --- the VFS writeback code will not always call
    ext4_write_inode().
    
    So we need to provide our own ext4_nfs_commit_metdata() method which
    calls ext4_write_inode() directly.
