Pull nilfs2 updates from Viacheslav Dubeyko:
"Fixes of syzbot reported issue and various small fixes in NILFS2
functionality.
- fix hung task in nilfs_transaction_begin() (Deepanshu Kartikey)
Reported by syzbot. The root cause is that user-supplied segment
numbers were not validated before nilfs_clean_segments() began
doing work; the range check on each segnum was performed deep
inside the call chain by nilfs_sufile_updatev(), which emits a
nilfs_warn() per invalid entry while still holding the segctor lock
and the sufile mi_sem.
Fix it by validating the contents of kbufs[4] in
nilfs_clean_segments() immediately after acquiring ns_segctor_sem
via nilfs_transaction_lock().
- fix a smatch warning in nilfs_mkdir() warn (Hongling Zeng)
This corrects a semantic issue related to the use of the
ERR_PTR macro that arose from a recent VFS change.
- fix a backing_dev_info reference leak (Shuangpeng Bai)
setup_bdev_super() initializes sb->s_bdev and takes a reference on
the block device backing_dev_info when assigning sb->s_bdi.
nilfs_fill_super() takes another reference to the same
backing_dev_info and stores it in sb->s_bdi again. The extra
reference is not paired with a matching bdi_put(), since
generic_shutdown_super() releases sb->s_bdi only once.
Drop the redundant bdi_get() in nilfs_fill_super(). The single
reference taken by setup_bdev_super() is enough and is released
during superblock shutdown"
