+metadata buffers; getting rid of those is responsibility of method, as it had
+been for ->delete_inode().
+	->drop_inode() returns int now; it's called on final iput() with inode_lock
+held and it returns true if filesystems wants the inode to be dropped.  As before,
+generic_drop_inode() is still the default and it's been updated appropriately.
+generic_delete_inode() is also alive and it consists simply of return 1.  Note that

+	clear_inode() is gone; use end_writeback() instead.  As before, it must
+be called exactly once on each call of ->evict_inode() (as it used to be for
+each call of ->delete_inode()).  Unlike before, if you are using inode-associated
+metadata buffers (i.e. mark_buffer_dirty_inode()), it's your responsibility to
+call invalidate_inode_buffers() before end_writeback().
+	No async writeback (and thus no calls of ->write_inode()) will happen
+after end_writeback() returns, so actions that should not overlap with ->write_inode()
+(e.g. freeing on-disk inode if i_nlink is 0) ought to be done after that call.
+
+	NOTE: checking i_nlink in the beginning of ->write_inode() and bailing out
+if it's zero is not *and* *never* *had* *been* enough.  Final unlink() and iput()
+may happen while the inode is in the middle of ->write_inode(); e.g. if you blindly
+free the on-disk inode, you may end up doing that while ->write_inode() is writing
+to it.
