History
Linus Torvalds cab7076a18 For this cycle we add support for the shutdown ioctl, which is 
primarily used for testing, but which can be useful on production
 systems when a scratch volume is being destroyed and the data on it
 doesn't need to be saved.  This found (and we fixed) a number of bugs
 with ext4's recovery to corrupted file system --- the bugs increased
 the amount of data that could be potentially lost, and in the case of
 the inline data feature, could cause the kernel to BUG.
 
 Also included are a number of other bug fixes, including in ext4's
 fscrypt, DAX, inline data support.
