A few updates to btrfs_mark_buffer_dirty(), with the most important one
to not allow a transaction to commit when we know there's some corruption
due to marking an extent buffer as dirty when its generation does not
match the current transaction's generation. More details on the change
logs of each patch.
Filipe Manana (3):
btrfs: abort transaction on generation mismatch when marking eb as dirty
btrfs: use btrfs_crit at btrfs_mark_buffer_dirty()
btrfs: mark transaction id check as unlikely at btrfs_mark_buffer_dirty()

From: Filipe Manana <fdmanana@suse.com>
When marking an extent buffer as dirty, at btrfs_mark_buffer_dirty(),
we check if its generation matches the running transaction and if not we
just print a warning. Such mismatch is an indicator that something really
went wrong and only printing a warning message (and stack trace) is not
enough to prevent a corruption. Allowing a transaction to commit with such
an extent buffer will trigger an error if we ever try to read it from disk
due to a generation mismatch with its parent generation.
So abort the current transaction with -EUCLEAN if we notice a generation
mismatch. For this we need to pass a transaction handle to
btrfs_mark_buffer_dirty() which is always available except in test code,
in which case we can pass NULL since it operates on dummy extent buffers
and all test roots have a single node/leaf (root node at level 0).

There's no need to use WARN() at btrfs_mark_buffer_dirty() to print an
error message, as we have the fs_info pointer we can use btrfs_crit()
which prints device information and makes the message have a more uniform
format. As we are already aborting the transaction we already have a stack
trace printed as well. So replace the use of WARN() with btrfs_crit().
Also slightly reword the message to use 'logical' instead of 'block' as
it's what is used in other error/warning messages.

At btrfs_mark_buffer_dirty(), having a transaction id mismatch is never
expected to happen and it usually means there's a bug or some memory
corruption due to a bitflip for example. So mark the condition as unlikely
to optimize code generation as well as to make it obvious for human
readers that it is a very unexpected condition.
