fsck_msdos , cluster numbers and alloc memory

因為一做fsck 就一堆 process 被kill，所以想找一下..
好像是 fat.c 的 readfat( ) 的 calloc:

fat = calloc(boot->NumClusters, sizeof(struct fatEntry))

拿 500G hd, 這兩個值 (NumClusters, sizeof fatEntry) 是 (15258357, 16)
拿1G, 是 (251155,16)
拿16G，是(1930019,16)
拿32G，是(1927187,16)

1G 的，把 boot sector data 有關

//system/bin/fsck_msdos(  687): NumSectors: 2013184, ClusterOffset: 3942, SecPerClust: 8
I//system/bin/fsck_msdos(  687): NumClusters:251155

32G:

I//system/bin/fsck_msdos(  687): NumSectors: 61700096, ClusterOffset: 30082, SecPerClust: 32
I//system/bin/fsck_msdos(  687): NumClusters:1927187

16G

I//system/bin/fsck_msdos(  687): NumSectors: 30910462, ClusterOffset: 30158, SecPerClust: 16
I//system/bin/fsck_msdos(  687): NumClusters:1930019

500G

I//system/bin/fsck_msdos(  687): NumSectors: 976773166, ClusterOffset: 238316, SecPerClust: 64
I//system/bin/fsck_msdos(  687): NumClusters:15258357
