would push out elements to fillup-read only when the time had come for them.
This could then trickle feed the read queue slowly, but fast enough to prevent
it from switching state.
allow CD-ROM/DVD-ROM/DB-ROM drives to read the media while still allowing them
to be appended later. It can also be seen as a way to make mountable
snapshots.
#include "opt_quota.h" which do exactly nothing. Speeds up kernel
compilation by 1.375*10^-20001 seconds. But leave the most moxious
comment in msdosfs_vfsops untouched.
1) Enhance write speed significantly on RMW media like CD-RW, DVD-RW but also
on the DVD+RW and all other ECC blocked media. Significant speedups of access
to the device for say compilation on the DVD. Streaming copy is also still at
maximum speed though vast amounts of directory copy work can show side effects
that appear it to slow down but are actually logical when you consider that
most small files are embedded into the descriptors itself.
2) explicit wait for the created RMW thread to spinup
old somewhat naive selection scheme that didn't allow different allocation
settings for nodes, directory information (FIDs) and data.
Also fix some curious side-effects of atime updates on RMW devices.
preliminary Metadata partition write support but its disabled still since
its not finished yet and not functioning correctly. All other formats are
checked and should work fine.
heavily fragmented files.
Also fixing some (rare) allocation bugs and function name streamlining.
Tested on harddisc, CD-RW and CD-R i.e. all three basic backend classes.
and DVD's behave like floppy discs. Writing is supported upto and including
version 2.01; version 2.50 and 2.60 will follow.
Also extending the UDF implementation to support symbolic links and
hardlinks.
Added are the mmcformat(8) tool to format rewritable CD/DVD discs and
newfs_udf(8).
Limitations:
all operations can be performed on the file system though the
sheduling is currently optimised for archiving workloads.
mv(1)/rename(2) is currently only implemented for non-directories.
