2000-07-26 Mark Kettenis <kettenis@gnu.org>
* Makefile (HURDLIBS): Reorder libs such that the threads lib
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.
2000-03-19 Roland McGrath <roland@baalperazim.frob.com>
* io.c: Comments.
* 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.
1999-11-24 Roland McGrath <roland@baalperazim.frob.com>
* storeio.c (trivfs_modify_stat): Clear writable bits if open store is
readonly, not just if we got the --readonly switch.
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'.
1999-07-11 Roland McGrath <roland@baalperazim.frob.com>
* 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.
1999-07-10 Roland McGrath <roland@baalperazim.frob.com>
* dev.c: Add #include <sys/mman.h> for munmap decl.
* pager.c: Likewise.
1999-07-03 Thomas Bushnell, BSG <tb@mit.edu>
* dev.c (dev_buf_fill): Use munmap instead of vm_deallocate.

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.
* 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.
1998-10-20 Roland McGrath <roland@baalperazim.frob.com>
* dev.c (dev_buf_fill): Add braces to silence gcc warning.
1998-07-20 Roland McGrath <roland@baalperazim.frob.com>
* storeio.c (main): Fix return type to int, and use return.
Wed Aug 20 14:07:05 1997 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>

pager_create properly.
* pager.c (service_paging_requests): New args for
ports_manage_port_operations_multithread.

* storeio.c (fsys_port_class, root_port_class, port_bucket,
trivfs_protid_portclasses, trivfs_protid_nportclasses,
