ext4: Don't update ctime for non-extent-mapped inodes
The VFS handles updating ctime, so we don't need to update the inode's ctime in ext4_splace_branch() to update the direct or indirect blocks. This was harmless when we did this in ext3, but in ext4, thanks to delayed allocation, updating the ctime in ext4_splice_branch() can cause the ctime to mysteriously jump when the blocks are finally allocated. Thanks to Björn Steinbrink for pointing out this problem on the git mailing list. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
