Jakub Kicinski e52972c11d net/tls: replace the sleeping lock around RX resync with a bit lock ... Commit 38030d7cb7 ("net/tls: avoid NULL-deref on resync during device removal") tried to fix a potential NULL-dereference by taking the context rwsem. Unfortunately the RX resync may get called from soft IRQ, so we can't use the rwsem to protect from the device disappearing. Because we are guaranteed there can be only one resync at a time (it's called from strparser) use a bit to indicate resync is busy and make device removal wait for the bit to get cleared. Note that there is a leftover "flags" field in struct tls_context already.
