Thanks, added to the ext4 patch queue, altough I did tighten up up your patch description slightly: ext4: fix null handler of ioctls in no journal mode The EXT4_IOC_GROUP_ADD and EXT4_IOC_GROUP_EXTEND ioctls should not flush the journal in no_journal mode. Otherwise, running resize2fs on a mounted no_journal partition triggers the following error messages: BUG: unable to handle kernel NULL pointer dereference at 00000014 IP: [<c039d282>] _spin_lock+0x8/0x19 *pde = 00000000 Oops: 0002 [#1] SMP Signed-off-by: Peng Tao <bergwolf@xxxxxxxxx> Signed-off-by: "Theodore Ts'o" <tytso@xxxxxxx> - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
