From: Linus Torvalds Date: Fri, 14 Jan 2011 21:26:18 +0000 (-0800) Subject: Turn d_set_d_op() BUG_ON() into WARN_ON_ONCE() X-Git-Tag: MMI-PSA29.97-13-9~21019 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6f7f7caab259026234277b659485d22c1dcb1ab4;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git Turn d_set_d_op() BUG_ON() into WARN_ON_ONCE() It's indicative of a real problem, and it actually triggers with autofs4, but the BUG_ON() is excessive. The autofs4 case is being fixed (to only set d_op in the ->lookup method) but not merged yet. In the meantime this gets the code limping along.
