Hi
Thank you very much for your help.
In the linux kernel version 2.4.X,
Does anybody mount a hard drive with MSDOS type file system ??
When I mount this hard drive using the command :
mount -t msdos /dev/hda1 /mnt/hd -o blocksize=1024
After mounting a hard disk, I read a file , and the system occours errors.
After I check the msdos file system in "usr/src/linux/fs/fat/cvf.c"
Iin the codes,
struct cvf_format bigblock_cvf={
:
:
:
default_fat_bmap,
NULL,
default_fat_file_write,
:
:
}
I check the data struct , the NULL field is defined a file_read callback
function. So , when I read a file , will cause the system error.
In the kernel version 2.2.17, I can mount a MSDOS filesystem with the
option
"-o blocksize=1024", and the driver can read/write two pages at the same
time. But in the kernel version 2.4.X, it doesn't work.
how two read/write two or more pages(blocks) at the same time in
the kernel version 2.4.X ??
Thanks
