fs/ocfs2/dlm/dlmthread.c:191:4-7: WARNING: Use BUG_ON
Use BUG_ON instead of a if condition followed by BUG.
Semantic patch information:
This makes an effort to find cases where BUG() follows an if
condition on an expression and replaces the if condition and BUG()
with a BUG_ON having the conditional expression of the if statement
as argument.
