[RFC,PATCH 0/2] Common struct clk implementation, v4
Hi all, These patches are an attempt to allow platforms to share clock code. At present, the definitions of 'struct clk' are local to platform code, which makes allocating and initialising cross-platform clock sources difficult, and makes it impossible to compile a single image containing support for two ARM pla... 4 Jun 2010 03:46

[RFC,PATCH 2/2] clk: Generic support for fixed-rate clocks
Since most platforms will need a fixed-rate clock, add one. This will also serve as a basic example of an implementation of struct clk. Signed-off-by: Jeremy Kerr <jeremy.kerr(a)canonical.com> --- include/linux/clk.h | 13 +++++++++++++ kernel/Makefile | 1 + kernel/clk.c | 25 +++++++++++++++... 4 Jun 2010 03:46

[patch 3/4] fs: scale files_lock
Improve scalability of files_lock by adding per-cpu, per-sb files lists, protected with an lglock. The lglock provides fast access to the per-cpu lists to add and remove files. It also provides a snapshot of all the per-cpu lists (although this is very slow). One difficulty with this approach is that a file can b... 4 Jun 2010 03:46

[patch 0/4] Initial vfs scalability patches again
OK, I realised what I was smoking last time. So I put down the pipe and went to score some stronger crack. And then: - reduced ifdefs as much as feasible - add more comments, avoided churn - vastly improved lock library code, works with lockdep - added helpers for file list iterations - lglock type for what was p... 4 Jun 2010 03:46

How do I ignore the changes made by CVS keyword substitution efficiently?
Look into the git attributes and filters, make a clean command that strips out the cvs/svn keywords.
