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

*inode, loff_t *offset, int origin)
      u64 lockend = i_size_read(inode);
      u64 start = *offset;

-    u64 len = i_size_read(inode);
+    u64 len;
      u64 last_end = 0;
      int ret = 0;


Thanks,
