Driver-Core: extend devnode callbacks to provide permissions

2009-09-19T19:50:38+00:00

This allows subsytems to provide devtmpfs with non-default permissions
for the device node. Instead of the default mode of 0600, null, zero,
random, urandom, full, tty, ptmx now have a mode of 0666, which allows
non-privileged processes to access standard device nodes in case no
other userspace process applies the expected permissions.

This also fixes a wrong assignment in pktcdvd and a checkpatch.pl complain.

vfs: Rename generic_file_aio_write_nolock

2009-09-14T15:08:15+00:00

generic_file_aio_write_nolock() is now used only by block devices and raw
character device. Filesystems should use __generic_file_aio_write() in case
generic_file_aio_write() doesn't suit them. So rename the function to
blkdev_aio_write() and move it to fs/blockdev.c.

block: Do away with the notion of hardsect_size

2009-05-22T21:22:54+00:00

Until now we have had a 1:1 mapping between storage device physical
block size and the logical block sized used when addressing the device.
With SATA 4KB drives coming out that will no longer be the case.  The
sector size will be 4KB but the logical block size will remain
512-bytes.  Hence we need to distinguish between the physical block size
and the logical ditto.

This patch renames hardsect_size to logical_block_size.

device create: char: convert device_create_drvdata to device_create

2008-10-16T16:24:42+00:00

Now that device_create() has been audited, rename things back to the
original call to be sane.

device create: char: convert device_create to device_create_drvdata

2008-07-22T04:54:41+00:00

device_create() is race-prone, so use the race-free
device_create_drvdata() instead as device_create() is going away.
