an off_t as size argument.
Implemented new function vm_cache_write_modified() which will write all
dirty pages of this cache back to disk (using the new vm_page_write_modified()
function).
Fixed warnings when compiled with debug output.

pages in a cache back using the store's write method. Doesn't optimize
disk access yet.

While we can tolerate the device driver to ignore the bytes argument when we
read from the device, we cannot do this for writes - now the code actually
takes this into account. Also added a comment about what to do when our own
driver is fixed :)
Implemented file_cache_sync().
file_cache_set_size() now uses vm_cache::virtual_size instead of the now
removed vnode_store::size. Also, it now resizes the vm_cache as well, so
that any no longer used pages are freed.
write_to_cache() now puts all pages in the modified list, so that they
can be written back easily.
Improved debug output.

vm_cache::virtual_size is now used by the file cache code.

dec_vnode_ref_count() now deletes the cache *after* calling the file system's
remove/release vnode function. Also, it will now write back any pending
changes in that cache before removing it.
Some cleanup.

Changed size argument of vm_cache_resize() from size_t to off_t.

Now, it will only notify the read requests do gather the data.

Inode::SetFileSize() now changes the size of the cache as well.

move code from use of boot_time to use of system_time_offset
added _user_get_tzfilename
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10192 a95241bf-73f2-0310-859d-f6bbb57e9c96
this should be factored in kernel core to only have a system_time_offset

That avoids starting a new transaction for no reason (which wouldn't do any harm,
but still, it's not necessary to do that at all).
log_entry::cached_blocks is no longer maintained or needed.

Also, it did not check the access permissions if the file already existed.
Removed check for INODE_NO_CACHE, as this no longer applies.

tests the libroot.so implementation, so it has to be run under Haiku to
test its implementation (it only prints out all directories, anyway).

Moved test main() into separate file under tests/.
Fixed warnings, some cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10181 a95241bf-73f2-0310-859d-f6bbb57e9c96
it is only tested on R5, but should make its way on Haiku too
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10178 a95241bf-73f2-0310-859d-f6bbb57e9c96
removed set_tzspecs, which was useless; now done in user_set_tzspecs

tzfilename is used to keep current timezone filename
isGMT is used to know how to handle rtc clock

modification code (used by ProposeDisplayMode) to adhere to one more timing constraint.
