• 609d7fa95   [PATCH] file: modify struct fown_struct to use a struct pid ... Browse Code »

  File handles can be requested to send sigio and sigurg to processes. By
  tracking the destination processes using struct pid instead of pid_t we make
  the interface safe from all potential pid wrap around problems.

• fa3536cc1   [PATCH] Use __read_mostly on some hot fs variables ... Browse Code »

  I discovered on oprofile hunting on a SMP platform that dentry lookups were
  slowed down because d_hash_mask, d_hash_shift and dentry_hashtable were in
  a cache line that contained inodes_stat. So each time inodes_stats is
  changed by a cpu, other cpus have to refill their cache line.

  This patch moves some variables to the __read_mostly section, in order to
  avoid false sharing. RCU dentry lookups can go full speed.

  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!
