Bottomley" <James.Bottomley@...e.de>, David Woodhouse <David.Woodhouse@...el.com>, linux-mtd@...ts.infradead.org, Linus Torvalds <torvalds@...ux-foundation.org>, Ingo Molnar <mingo@...e.hu>, Benjamin Herrenschmidt <benh@...nel.crashing.org>, linuxppc-dev@...abs.org, Corey Minyard <minyard@....org>, openipmi-developer@...ts.sourceforge.net, Takashi Iwai <tiwai@...e.de>, Jens Axboe <axboe@...nel.dk> Subject: [PATCH 0/7] BKL mass-conversion to mutex This is one out of five topic branches in my BKL removal series that I would like to get into linux-next as a preparation for merging into 2.6.37. Based on a discussion with Ingo Molnar, this series converts many drivers that only have a single file using the BKL to use a private mutex instead. All these patches except for the last two have been reviewed before. This is safe because they all use the BKL only to protect their basic file operations and they take it as the outermost lock. Consequently, we do not run into lock-order problem or recursion. Using a script that works for all these drivers gives me reasonable confidence in the approach, since it avoids typos and other common mistakes from sloppiness.
