    gfs2: perform quota checks against allocation parameters · b8fbf471

    Use struct gfs2_alloc_parms as an argument to gfs2_quota_check()
    and gfs2_quota_lock_check() to check for quota violations while
    accounting for the new blocks requested by the current operation
    in ap->target.
    Previously, the number of new blocks requested during an operation
    were not accounted for during quota_check and would allow these
    operations to exceed quota. This was not very apparent since most
    operations allocated only 1 block at a time and quotas would get
    violated in the next operation. i.e. quota excess would only be by
    1 block or so. With fallocate, (where we allocate a bunch of blocks
    at once) the quota excess is non-trivial and is addressed by this
