Bug Description

SRU Justification/Impact: The upstream process for stable tree updates is quite similar in scope to the Ubuntu SRU process, e.g., each patch has to demonstrably fix a bug, and each patch is vetted by upstream by originating either directly from Linus' tree or in a minimally backported form of that patch. The upstream stable patch set is now available. It should be included in the Ubuntu kernel as well.




The Upstream Stable Kernel brings in the following 91 patches:

* ext4: Fix memory leak fix when mounting an ext4 filesystem
* ext4: Avoid null pointer dereference when decoding EROFS w/o a journal
* jbd2: Fail to load a journal if it is too short
* jbd2: round commit timer up to avoid uncommitted transaction
* ext4: fix journal ref count in move_extent_par_page
* ext4: Fix bugs in mballoc's stream allocation mode
* ext4: Avoid group preallocation for closed files
* jbd2: Annotate transaction start also for jbd2_journal_restart()
* ext4: Fix possible deadlock between ext4_truncate() and ext4_get_blocks()
* ext4: reject too-large filesystems on 32-bit kernels
* ext4: Add feature set check helper for mount & remount paths
* ext4: Add missing unlock_new_inode() call in extent migration code
* ext4: Allow rename to create more than EXT4_LINK_MAX subdirectories
* ext4: Limit number of links that can be created by ext4_link()
