      f2fs: relax async discard commands more · 4e6a8d9b
      Jaegeuk Kim authored
      This patch relaxes async discard commands to avoid waiting its end_io during
      checkpoint.
      Instead of waiting them during checkpoint, it will be done when actually reusing
      them.
      
      Test on initial partition of nvme drive.
      
       # time fstrim /mnt/test
      
      Before : 6.158s
      After : 4.822s

      f2fs: drop exist_data for inline_data when truncated to 0 · bb95d9ab
      Jaegeuk Kim authored
      A test program gets the SEEK_DATA with two values between
      a new created file and the exist file on f2fs filesystem.
      
      F2FS filesystem,  (the first "test1" is a new file)
      SEEK_DATA size != 0 (offset = 8192)
      SEEK_DATA size != 0 (offset = 4096)
      
      PNFS filesystem, (the first "test1" is a new file)
      SEEK_DATA size != 0 (offset = 4096)
      SEEK_DATA size != 0 (offset = 4096)
      
      int main(int argc, char **argv)

              }
