is related to LU-10467 use standard linux wait_event macros Resolved
Severity: 3
Rank (Obsolete): 9223372036854775807

 Description   

New upstream kernels added additional checking to CONFIG_DEBUG_ATOMIC__SLEEP to ensure no blocking calls are made while in not RUNNIG state,as otherwise the state could be lost.

For us offenders are in __l_wait_event for callbacks,
in libcfs_debug_dumplog and in libcfs_sock_accept
