David Sterba 8bb808c6ad btrfs: don't print stack trace when transaction is aborted due to ENOMEM ... Add ENOMEM among the error codes that don't print stack trace on transaction abort. We've got several reports from syzbot that detects stacks as errors but caused by limiting memory. As this is an artificial condition we don't need to know where exactly the error happens, the abort and error cleanup will continue like e.g. for EIO. As the transaction aborts code needs to be inline in a lot of code, the implementation cases about minimal bloat. The error codes are in a separate function and the WARN uses the condition directly. This increases the code size by 571 bytes on release build. Alternatives considered: add -ENOMEM among the errors, this increases size by 2340 bytes, various attempts to combine the WARN and helper calls, increase by 700 or more bytes.
