ext4: Fix insertion point of extent in mext_insert_across_blocks() If the leaf node has 2 extent space or fewer and EXT4_IOC_MOVE_EXT ioctl is called with the file offset where after the 2nd extent covers, mext_insert_across_blocks() always tries to insert extent into the first extent. As a result, the file gets corrupted because of wrong extent order. The patch fixes this problem. Signed-off-by: Akira Fujita <a-fujita@rs.jp.nec.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
