The patch set is a tiny subset of the complete set of patches to clean up the locking bugs, switch to unlocked_ioctl and the like for watchdog drivers These specific ones are the ones that - Remove use of inb_p() on PCI bus which is unsafe with some newer boxes - Switch from using a sempahore held across the return to user space for watchdog locking - and thus help remove more users of down_trylock. drivers/watchdog/ar7_wdt.c | 29 ++-- drivers/watchdog/it8712f_wdt.c | 77 ++++------ drivers/watchdog/s3c2410_wdt.c | 148 +++++++++++--------- drivers/watchdog/sc1200wdt.c | 205 +++++++++++++++------------ drivers/watchdog/wdt.c | 176 ++++++++++++----------- drivers/watchdog/wdt_pci.c | 301 +++++++++++++++++++++++----------------- 6 files changed, 503 insertions(+), 433 deletions(-) -- "The IETF already has more than enough RFCs that codify the obvious, make stupidity illegal, support truth, justice, and the IETF way, and generally demonstrate the author is a brilliant and valuable Contributor to The Standards Process." -- Vernon Schryver
