2013-02-27	hlist: drop the node parameter from iterators	Sasha Levin	1	-2/+1
	I'm not sure why, but the hlist for each entry iterators were conceived list_for_each_entry(pos, head, member) The hlist ones were greedy and wanted an extra parameter: hlist_for_each_entry(tpos, pos, head, member) Why did they need an extra pos parameter? I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually. The semantic patch which is mostly the work of Peter Senna Tschudin is here: @@ iterator name hlist_for_each_entry, hlist_for_each_entry_continue, hlist_for_each_entry_from, hlist_for_each_entry_rcu, hlist_for_each_entry_rcu_bh, hlist_for_each_entry_continue_rcu_bh, for_each_busy_worker, ax25_uid_for_each, ax25_for_each, inet_bind_bucket_for_each, sctp_for_each_hentry, sk_for_each, sk_for_each_rcu, sk_for_each_from, sk_for_each_safe, sk_for_each_bound, hlist_for_each_entry_safe, hlist_for_each_entry_continue_rcu, nr_neigh_for_each, nr_neigh_for_each_safe, nr_node_for_each, nr_node_for_each_safe, for_each_gfn_indirect_valid_sp, for_each_gfn_sp, for_each_host; type T; expression a,c,d,e; identifier b; statement S; @@ -T b; <+... when != b ( hlist_for_each_entry(a, - b, c, d) S \| hlist_for_each_entry_continue(a, - b, c) S \| hlist_for_each_entry_from(a, - b, c) S \| hlist_for_each_entry_rcu(a, - b, c, d) S \| hlist_for_each_entry_rcu_bh(a, - b, c, d) S \| hlist_for_each_entry_continue_rcu_bh(a, - b, c) S \| for_each_busy_worker(a, c, - b, d) S \| ax25_uid_for_each(a, - b, c) S \| ax25_for_each(a, - b, c) S \| inet_bind_bucket_for_each(a, - b, c) S \| sctp_for_each_hentry(a, - b, c) S \| sk_for_each(a, - b, c) S \| sk_for_each_rcu(a, - b, c) S \| sk_for_each_from -(a, b) +(a) S + sk_for_each_from(a) S \| sk_for_each_safe(a, - b, c, d) S \| sk_for_each_bound(a, - b, c) S \| hlist_for_each_entry_safe(a, - b, c, d, e) S \| hlist_for_each_entry_continue_rcu(a, - b, c) S \| nr_neigh_for_each(a, - b, c) S \| nr_neigh_for_each_safe(a, - b, c, d) S \| nr_node_for_each(a, - b, c) S \| nr_node_for_each_safe(a, - b, c, d) S \| - for_each_gfn_sp(a, c, d, b) S + for_each_gfn_sp(a, c, d) S \| - for_each_gfn_indirect_valid_sp(a, c, d, b) S + for_each_gfn_indirect_valid_sp(a, c, d) S \| for_each_host(a, - b, c) S \| for_each_host_safe(a, - b, c, d) S \| for_each_mesh_entry(a, - b, c, d) S ) ...+> [akpm@linux-foundation.org: drop bogus change from net/ipv4/raw.c] [akpm@linux-foundation.org: drop bogus hunk from net/ipv6/raw.c] [akpm@linux-foundation.org: checkpatch fixes] [akpm@linux-foundation.org: fix warnings] [akpm@linux-foudnation.org: redo intrusive kvm changes] Tested-by: Peter Senna Tschudin <peter.senna@gmail.com> Acked-by: Paul E.

2011-01-07	fs: dcache per-inode inode alias locking	Nick Piggin	1	-2/+2
	dcache_inode_lock can be replaced with per-inode locking. Use existing inode->i_lock for this. This is slightly non-trivial because we sometimes need to find the inode from the dentry, which requires d_inode to be stabilised (either with refcount or d_lock).

2008-02-07	iget: stop AFFS from using iget() and read_inode()	David Howells	1	-2/+4
	Stop the AFFS filesystem from using iget() and read_inode(). Replace affs_read_inode() with affs_iget(), and call that instead of iget(). affs_iget() then uses iget_locked() directly and returns a proper error code instead of an inode in the event of an error. affs_fill_super() returns any error incurred when getting the root inode instead of EINVAL.

	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!
