From 08b52706d505658eac0962d215ff697f898bbc13 Mon Sep 17 00:00:00 2001 From: Konstantin Khlebnikov Date: Fri, 22 Feb 2013 16:34:40 -0800 Subject: mm/rmap: rename anon_vma_unlock() => anon_vma_unlock_write() The comment in commit 4fc3f1d66b1e ("mm/rmap, migration: Make rmap_walk_anon() and try_to_unmap_anon() more scalable") says: | Rename anon_vma_[un]lock() => anon_vma_[un]lock_write(), | to make it clearer that it's an exclusive write-lock in | that case - suggested by Rik van Riel. But that commit renames only anon_vma_lock() Signed-off-by: Konstantin Khlebnikov Cc: Ingo Molnar Reviewed-by: Rik van Riel Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- mm/mmap.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'mm/mmap.c') diff --git a/mm/mmap.c b/mm/mmap.c index 28416f6b8dd..318e121affd 100644 --- a/mm/mmap.c +++ b/mm/mmap.c @@ -809,7 +809,7 @@ again: remove_next = 1 + (end > next->vm_end); anon_vma_interval_tree_post_update_vma(vma); if (adjust_next) anon_vma_interval_tree_post_update_vma(next); - anon_vma_unlock(anon_vma); + anon_vma_unlock_write(anon_vma); } if (mapping) mutex_unlock(&mapping->i_mmap_mutex); @@ -3017,7 +3017,7 @@ static void vm_unlock_anon_vma(struct anon_vma *anon_vma) if (!__test_and_clear_bit(0, (unsigned long *) &anon_vma->root->rb_root.rb_node)) BUG(); - anon_vma_unlock(anon_vma); + anon_vma_unlock_write(anon_vma); } } -- cgit v1.2.3
