2005-10-30[PATCH] reduce sizeof(struct file)Eric Dumazet
Now that RCU applied on 'struct file' seems stable, we can place f_rcuhead in a memory location that is not anymore used at call_rcu(&f->f_rcuhead, file_free_rcu) time, to reduce the size of this critical kernel object. The trick I used is to move f_rcuhead and f_list in an union called f_u The callers are changed so that f_rcuhead becomes f_u.fu_rcuhead and f_list becomes f_u.f_list Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-07-07[PATCH] set mnt_namespace in the correct placeMiklos Szeredi
This patch sets ->mnt_namespace where it's actually added to the namespace. Previously mnt_namespace was set in do_kern_mount() even if the filesystem was never added to any process's namespace (most kernel-internal filesystems). This discrepancy doesn't actually cause any problems, but it's cleaner if mnt_namespace is NULL for these non exported filesystems.

2005-06-23[PATCH] O(1) sb list traversing on syncsKirill Korotaev
This patch removes O(n^2) super block loops in sync_inodes(), sync_filesystems() etc. in favour of using __put_super_and_need_restart() which I introduced earlier. We faced a noticably long freezes on sb syncing when there are thousands of super blocks in the system.

There is a memory leak during mount when CONFIG_SECURITY is enabled and mount options are specified. Signed-off-by: Gerald Schaefer <geraldsc@de.ibm.com> Acked-by: James Morris <jmorris@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

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!
