May be remounting the file system in read only mode will help.
try this:
# mount -o remount,ro <filesystem>
Yes this works, after remounting the file system in read only mode you
cant create new files and
you cant even write anything. I hope that helps.

as far as i have understood it is not freezing the file system but
it
is only freezing the write operation on block device
had it been freezing the file system inode creation would also block

I used a kernel module to freeze the file system using the
function freeze_bdev
but when i am try to use touch command on the file system i am
able to
create the files.
even read requests are served immediately
only the write requests are being blocked
until i call the thaw function
can i have an explanation for this

Hello,
I want to freeze a file system. I have seen a field in vfs
superblock
s_frozen.
But i am clue less about freezing the file system using that.
freeze_bdev function ( fs/buffer.c) lock a filesystem and force
it into a
consistent state ...
Above function use s_frozen flag to freez the file system ...
