Andriy Gapon 61548876b1 kdb_backtrace: use stack_print_ddb instead of stack_print ... This is a followup to r212964. stack_print call chain obtains linker sx lock and thus potentially may lead to a deadlock depending on a kind of a panic. stack_print_ddb doesn't acquire any locks and it doesn't use any facilities of ddb backend. Using stack_print_ddb outside of DDB ifdef required taking a number of helper functions from under it as well. It is a good idea to rename linker_ddb_* and stack_*_ddb functions to have 'unlocked' component in their name instead of 'ddb', because those functions do not use any DDB services, but instead they provide unlocked access to linker symbol information. The latter was previously needed only for DDB, hence the 'ddb' name component. Alternative is to ditch unlocked versions altogether after implementing proper panic handling: 1. stop other cpus upon a panic 2. make all non-spinlock lock operations (mutex, sx, rwlock) be a no-op when panicstr != NULL Suggested by: mdf Discussed with: attilio MFC after: 2 weeks		2010-09-22 06:45:07 +00:00
