[PATCH 5.4 534/658] ext4: initialize quota before expanding inode in setproject ioctl

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jan Kara <jack@xxxxxxx>

commit 1485f726c6dec1a1f85438f2962feaa3d585526f upstream.

Make sure we initialize quotas before possibly expanding inode space
(and thus maybe needing to allocate external xattr block) in
ext4_ioctl_setproject(). This prevents not accounting the necessary
block allocation.
