Summary
nilfs2: handle inconsistent state in nilfs_btnode_create_block()
Details

In the Linux kernel, the following vulnerability has been resolved:

nilfs2: handle inconsistent state in nilfsbtnodecreate_block()

Syzbot reported that a buffer state inconsistency was detected in nilfsbtnodecreate_block(), triggering a kernel bug.

It is not appropriate to treat this inconsistency as a bug; it can occur if the argument block address (the buffer index of the newly created block) is a virtual block number and has been reallocated due to corruption of the bitmap used to manage its allocation state.

So, modify nilfsbtnodecreate_block() and its callers to treat it as a possible filesystem error, rather than triggering a kernel bug.
