Hi,
I have a suggestion for 2.5 (and an almost working patch): isn't it
about time to introduce a bdev_t structure that contains all the
information that is scattered over lots of places?
That would be:
struct block_device
struct gendisk
struct sec_size
struct blk_dev_struct
read_ahead
blk_dev_

I tried vfat on a MO drive with 1KByte sectors - it doesn't work. I also

Hi,
While trying to get affs working again, I noticed that the current
cont_prepare_write is hardly working, if you write to a file in steps of
1024, the bytes pointer is never updated resulting in an endless loop.
Below is a fixed version, that also removes the bogus tricks to the
bytes ptr. I a
Hi,
Instead of all the kernel locks during block allocations, can't we
simply delay the inode truncate operation until the file is closed? All
we need is further inode field i_realsize, that is compared at close
time with i_size. It's also useful for other fs that don't support holes
and we get r

Hi,
I know that topic come up before, but I have an idea how preallocation
could be implemented. Basically I want to make the mechanism in ext2
(that is only internally used for file preallocation) generally
available. I think it should be possible to split the get_block
operation into a block al
