Btrfs devel - Aug 2011 - don't fetch the inode size beforehand.

Hello,

I think we don''t need to fetch the inode size in advance. :-P.

diff --git a/fs/btrfs/file.c b/fs/btrfs/file.c
index e7872e4..f8ad957 100644
--- a/fs/btrfs/file.c
+++ b/fs/btrfs/file.c
@@ -1698,7 +1698,7 @@ static int find_desired_extent(struct inode 
*inode, loff_t *offset, int origin)
      u64 lockend = i_size_read(inode);
      u64 start = *offset;
      u64 orig_start = *offset;
-    u64 len = i_size_read(inode);
+    u64 len;
      u64 last_end = 0;
      int ret = 0;


Thanks,
-Jeff

yes, the value is not used and rewritten a few lines below anyway.
Please send a patch with proper header and signed-off line to be
accepted.
