Analyze and fix the following issue in the Linux kernel code: btrfs: mark transaction id check as unlikely at btrfs_mark_buffer_dirty()
Problem Details: 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 ...
