[PATCH 00/29] dev->struct_mutex crusade, once more

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

Since Daniel Stone pointed out in the last round that I fumbled one locked vs.
unlocked case I audited all the drivers once more and uprooted a bunch more
offenders. They're mostly in error paths, but in case anyone wants to pick them
up I put them at the beginning of the patch series.

Again review, comments and acks highly welcome. I'd like to get this all in for
4.5 if possible, and will send out a pull request to Dave with the leftovers.

Cheers, Daniel
