bpp: bkl pushdown · 5e9829ad

Jonathan Corbet authored May 16, 2008

Put explicit lock_kernel() calls into bpp_open().  It has locking, but I'm
not convinced it won't race with ioctl().

Add "no BKL needed" comments to several drivers · d21c95c5

Jonathan Corbet authored May 16, 2008

This documents the fact that somebody looked at the relevant open()
functions and concluded that, due to their trivial nature, no locking was
needed.

usbcore: cdev lock_kernel() pushdown · 20613f24

Jonathan Corbet authored May 15, 2008

usb_open() is protected by a down_read(&minor_rwsem), but I'm not sure I
trust it to protect everything including subsidiary open() functions.
