This silences some Sparse warnings:
fs/jbd2/transaction.c:135:69: warning: incorrect type in argument 2 (different base types)
fs/jbd2/transaction.c:135:69:    expected restricted gfp_t [usertype] flags
fs/jbd2/transaction.c:135:69:    got int [signed] gfp_mask

This has been merged into the ext4 tree (a while ago, actually, but it
looks like I forgot to send an e-mail ack).
