Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

blockgroup_lock.h: simplify definition of NR_BG_LOCKS We can use ilog2() to more easily produce the desired NR_BG_LOCKS. This works because ilog2() is evaluated at compile-time when its argument is a compile-time constant. I did not change the chosen NR_BG_LOCKS values.

fs: introduce bgl_lock_ptr() As suggested by Andreas Dilger, introduce a bgl_lock_ptr() helper in <linux/blockgroup_lock.h> and add separate sb_bgl_lock() helpers to filesystem specific header files to break the hidden dependency to struct ext[234]_sb_info. Also, while at it, convert the macros to static inlines to try make up for all the times I broke Andrew Morton's tree.

blockgroup_lock.h: remove debris from bgl_lock_ptr() conversion An obsolete comment and extra parentheses were left over from when the sb_bgl_lock() macro was replaced with the bgl_lock_ptr() function.
