Revert "net/rds: Avoid potential use after free in rds_send_remove_from_sock"

2021-04-24T16:32:35Z

This reverts commit 0c85a7e87465f2d4cbc768e245f4f45b2f299b05. The games with 'rm' are on (two separate instances) of a local variable, and make no difference. Quoting Aditya Pakki: "I was the author of the patch and it was the cause of the giant UMN revert. The patch is garbage and I was unaware of the steps involved in retracting it. I *believed* the maintainers would pull it, given it was already under Greg's list. The patch does not introduce any bugs but is pointless and is stupid. I accept my incompetence and for not requesting a revert earlier." Link: https://lwn.net/Articles/854319/ Requested-by: Aditya Pakki Cc: Santosh Shilimkar Cc: David S.
