1999-11-20 Roland McGrath <roland@baalperazim.frob.com>
* dev.c (dev_read, dev_write): In DEV->inhibit_cache case,
handle zero (i.e. unknown) block_size by treating it as 1.
Use shift and bitwise-and rather than multiply and modulus
for block size arithmetic, since it's a known power of two.
1999-11-14 Roland McGrath <roland@baalperazim.frob.com>
* io.c (trivfs_S_file_get_storage_info): Fail with EOPNOTSUPP when
there is no store open.
* storeio.c (check_open_hook): Don't check for D_NO_SUCH_DEVICE here.
Translation to ENXIO now done in libstore.
* dev.h (struct dev): New member `enforced'.
* storeio.c (enforce_store): New variable.
(options, parse_opt, trivfs_append_args): Grok new option
--enforced/-e to set enforce_store.
(check_open_hook): Set DEVICE->enforced from enforce_store.
* io.c (trivfs_S_file_get_storage_info): If DEV->enforced is set
and the store flags lack STORE_ENFORCED, then return STORAGE_OTHER.
1999-09-13 Roland McGrath <roland@baalperazim.frob.com>
* io.c: Reverted changes related to io_map_segment.
1999-09-07 Thomas Bushnell, BSG <tb@mit.edu>
* io.c (trivfs_S_io_map): Renamed to ...
(trivfs_S_io_map_segment): ... here, and accept parameter `index'.

* dev.c (dev_read: ensure_buf): Fix sloppy bugs in last change.
1999-07-09 Thomas Bushnell, BSG <tb@mit.edu>
* dev.c (dev_open): Use mmap instead of vm_allocate.
(dev_read): Likewise.

* pager.c (pager_write_page): Likewise.
1999-05-23 Roland McGrath <roland@baalperazim.frob.com>
* storeio.c (check_open_hook): Translate D_NO_SUCH_DEVICE to ENXIO.
1999-05-09 Mark Kettenis <kettenis@gnu.org>
* pager.c (dev_stop_paging): Do not try to count ports in
PAGER_PORT_BUCKET if it has not been created.
1999-04-30 Mark Kettenis <kettenis@gnu.org>
* storeio.c (trivfs_modify_stat): Do not assume that we have the
device open in the caculation of st_mode. If the device is not
open, only return S_IFCHR if inhibit_cache is set.
1999-01-31 Roland McGrath <roland@baalperazim.frob.com>
* storeio.c (trivfs_modify_stat): Return S_IFCHR if block size is 1.
* storeio.c (trivfs_modify_stat): Return S_IFCHR iff inhibit_cache
set, otherwsie S_IFBLK. For a block-addressed device, S_IFCHR means
"must do whole-block i/o".
1999-01-28 Roland McGrath <roland@baalperazim.frob.com>
* io.c (trivfs_S_file_syncfs): Fix inverted test.
Reported by OKUJI Yoshinori <okuji@kuicr.kyoto-u.ac.jp>.

(dev_read, dev_write): If DEV->inhibit_cache is set, allow only
whole-block i/o: EINVAL for non-whole-block attempts.

make our own pager; if store_map returns EOPNOTSUPP, so do we.
