* dev.c (dev_buf_discard): Don't check AMOUNT if store_write failed.

* 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.
2000-07-26* Makefile (HURDLIBS): Reorder libs such that the threads libMark Kettenis
comes before the ports lib. This makes sure the functions in libthreads properly override the stubs in libports with the new dynamic linker semantics in glibc 2.2.

* 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.

* storeio.c (trivfs_modify_stat): Clear writable bits if open store is readonly, not just if we got the --readonly switch.

* 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.

* 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".
