      quota: Add quota reservation support · f18df228
      Mingming Cao 提交于
      Delayed allocation defers the block allocation at the dirty pages
      flush-out time, doing quota charge/check at that time is too late.
      But we can't charge the quota blocks until blocks are really allocated,
      otherwise users could get overcharged after reboot from system crash.
      
      This patch adds quota reservation for delayed allocation. Quota blocks
      are reserved in memory, inode and quota won't gets dirtied until later
      block allocation time.
