| | | | | | | | | | | | | | | | | | | | | | pointers. Neither is portable, but "correct" casts to integral types are much uglier - they lead to expressions like ptr = (struct struct_with_too_long_a_name *)(void *)(uintptr_t) ((uintptr_t)(void *)ptr + offset); Here the cast to the struct pointer is to match the surrounding style of this file (and not depend on C's feature of properly converting `void *' on assignment or cast), the `void *' casts are because uintptr_t is only specified to work on `void *' pointers (I missed this in about 100 lines of previous changes from [u]long to [u]intptr_t), the outer cast to a uintptr_t is in case the addition promoted the type, and the inner cast to a uintptr_t corresponds to the one cast to an integer in the original code. Don't depend on gcc's feature of casting lvalues. Notes: svn path=/head/; revision=38346

* Use the slice interfaces for SCSI cdroms. This centralizes handlingBruce Evans1998-07-301-203/+115
| | | | | | | | | | | | | | of some disk ioctls and uniformizes bounds checking in the strategy routine. EOF handling got fixed as a side effect. The changes are similar to old changes for SCSI disks, except slices and labels are not searched for on the disk and the in-core label has a few more details (mostly just for backwards compatibility). Bugs in the in-core label had to be fixed to get dsopen() to accept it. The slice interfaces had to support large sectors for all this to work. Notes: svn path=/head/; revision=37975
* Added a flags arg to dsopen() and updated drivers. The DSO_ONESLICEBruce Evans1998-07-302-4/+4
| | | | | | | | | | | | | | and DSO_NOLABELS flags prevent searching for slices and labels respectively. Current drivers don't set these flags. When DSO_NOLABELS is set, the in-core label for the whole disk is cloned to create an in-core label for each slice. This gives the correct result (a good in-core label for the compatibility slice) if DSO_ONESLICE is set or only one slice is found, but usually gives broken labels otherwise, so DSO_ONESLICE should be set if DSO_NOLABELS is set.

| | | | | | | | | | | | | | | | | | | | | There is only cdevsw (which should be renamed in a later edit to deventry or something). cdevsw contains the union of what were in both bdevsw an cdevsw entries. The bdevsw[] table stiff exists and is a second pointer to the cdevsw entry of the device. it's major is in d_bmaj rather than d_maj. some cleanup still to happen (e.g. dsopen now gets two pointers to the same cdevsw struct instead of one to a bdevsw and one to a cdevsw). rawread()/rawwrite() went away as part of this though it's not strictly the same patch, just that it involves all the same lines in the drivers. cdroms no longer have write() entries (they did have rawwrite (?)). tapes no longer have support for bdev operations.
