| H A D | alloc.c | c18b812d Mon Aug 17 22:44:07 CDT 2009 Tao Ma <tao.ma@oracle.com> ocfs2: Make transaction extend more efficient.
In ocfs2_extend_rotate_transaction, op_credits is the orignal
credits in the handle and we only want to extend the credits
for the rotation, but the old solution always double it. It
is harmless for some minor operations, but for actions like
reflink we may rotate tree many times and cause the credits
increase dramatically. So this patch try to only increase
the desired credits.
