* dev.h (struct dev): New member `no_fileio' (flag). * storeio.c (options): Add --no-file-io/-F. (parse_opt): Parse it to set PARAMS->dev->no_fileio. (trivfs_append_args): Add --no-file-io if it's set. * dev.c (dev_open): Pass STORE_NOFILEIO flag if DEV->no_fileio is set.

* dev.h (struct dev): New member nperopens. * storeio.c (open_hook): Hold device lock and check if this is the first open. If yes, activate the store. (close_hook): Hold global_lock and check if this was the last open. If yes, inactivate the store. * dev.c (dev_open): Open the store with STORE_INACTIVE (in store_parsed_open as well as in store_create).

* dev.c (dev_open): Add missing argument `classes' to invocation of store_create. * dev.h: Include <hurd/trivfs.h> for struct trivfs_control.

* storeio.c (parse_opt): Set PARAMS->store_params.store_optional. (storeio_fsys): New global variable. (main): Use it. * dev.h: Declare it. * dev.c (dev_open): If DEV->store_name is null, open the underlying node using store_create.

* dev.h (struct dev): New members store_name, readonly, rdev. (dev_is_readonly): New inline function. * dev.c (dev_open): Take just one arg, a struct dev whose store==0. (dev_close): Shut down the store, but leave DEV intact with store==0. * storeio.c (struct storeio_argp_params): New type. (device, device_lock, store_name): Variables removed. (readonly, inhibit_cache, enforce_store, rdev): Likewise. These are all now members in struct storeio_argp_params or struct dev; rdev now uses dev_t instead of int. (parse_opt): Find a struct storeio_argp_params in STATE->input and fill it in accordingly. Use makedev macro to construct rdev. (trivfs_append_args): Find options in struct dev off control hook. Use major, minor macros. (main): Make DEVICE a local here, and point FSYS->hook at it. Don't modify trivfs_allow_open. (getroot_hook): New static function. (trivfs_getroot_hook): New variable, initialized to that. (check_open_hook): Find struct dev in CNTL->hook and use new dev_open interface. Use dev_is_readonly. (open_hook): Find struct dev in PEROPEN->cntl->hook and check DEV->store. (trivfs_modify_stat): Find struct dev in CRED->po->cntl->hook. Use dev_is_readonly. (trivfs_goaway): Find struct dev in FSYS->hook and use its lock. (trivfs_S_fsys_syncfs): Find struct dev in CNTL->hook.

* 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.

* storeio.c (options): New option -c/--no-cache. (inhibit_cache): New variable. (parse_opt): Make -c set it. (trivfs_append_args): Report --no-cache if set. (check_open_hook): Pass inhibit_cache flag to dev_open. * dev.h (struct dev): New member `inhibit_cache'. (dev_open): Update decl. * dev.c (dev_open): Take new arg inhibit_cache, store in new dev. If set, don't initialize buf_offs, io_lock, pager, pager_lock. (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.
1997-07-17(dev_get_memory_object):Miles Bader
Add PROT arg.
1996-09-23(struct dev, dev_read, dev_write):Miles Bader
Use void * buffers.
