Fixes deadlock described in this bug: https://syzkaller.appspot.com/bug?extid=e953a8f3071f5c0a28fd. Specific crash report here: https://syzkaller.appspot.com/text?tag=CrashReport&x=14670e07980000. This bug is a false positive lockdep warning since gtp and smc use completely different socket protocols. Lockdep thinks that lock_sock() in smc will deadlock with gtp's lock_sock() acquisition. Adding lockdep annotations on smc socket creation prevents these false positives. Daniel Yang (2): Patch from D. Wythe <alibuda@xxxxxxxxxxxxxxxxx> Move lockdep annotation to separate function for readability. net/smc/smc_inet.c | 29 ++++++++++++++++++++++++++++- 1 file changed, 28 insertions(+), 1 deletion(-) -- 2.39.2
