* 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>.
1999-01-27 Roland McGrath <roland@baalperazim.frob.com>
* storeio.c (options): New option -c/--no-cache.
(inhibit_cache): New variable.

(dev_read, dev_write): If DEV->inhibit_cache is set, allow only
whole-block i/o: EINVAL for non-whole-block attempts.
* pager.c (dev_get_memory_object): If DEV->inhibit_cache is set, don't
make our own pager; if store_map returns EOPNOTSUPP, so do we.

* dev.h (dev_get_memory_object): Add PROT arg.
1997-07-16 Miles Bader <miles@gnu.ai.mit.edu>
* pager.c (pager_read_page): Initialize READ to 0.
* pager.c (dev_get_memory_object): Implement correctly.
(dev_stop_paging): Work entirely by flushing user pagers; don't kill pager.
(pager_clear_user_data): Zero our pointer to the pager.
