Prev: [PATCH] IR/lirc_dev: fix locking in lirc_dev_fop_read
Next: [PATCH 5/7] block: remove BKL from BLKROSET and BLKFLSBUF
From: Arnd Bergmann on 7 Jul 2010 11:00 This series removes the big kernel lock from the common block layer code by pushing it into the individual device drivers. This version incorporates further changes to address comments from Christoph Hellwig and Sam Ravnborg, many thanks for the valuable feedback! I'd like to get this into 2.6.36 in order to remove the BKL from all the core kernel code. Once Christoph is happy with the series, in particular the third patch, I'd like to add it to linux-next for broader testing, preferrably though Jens Axboe's linux-2.6-block.git tree.
