Folks, updated namespace patch is on
ftp.math.psu.edu/pub/viro/namespaces-b-S3-pre8.gz
It took longer than I expected - sorry about that.
News:
* fix for long-standing races between rename() and umount()
* much better scalability for case of multiple namespaces (cost of
traversing mountpoints is nearly constant instead of O(number of
namespaces)).
* recursive bind (i.e. bind with submounts - pass MS_BIND|MS_REC in
flags)
* sane refcounting for FS_SINGLE filesystems
* fixes for assorted bugs in previous version
* real cleanup of fs/super.c logics. Hell, it's almost documentable
now. Thing separated into namespace.c (vfsmount handling) and
super.c - both became readable.
It seems to be working here, but it obviously needs more testing. Patch
is against 2.4.3-pre8. As far as I'm concerned design-wise it's pretty close
to final - next pieces will go as incremental to it.
I'll start posting documentation when I'll be back from San Jose. Please,
help testing the thing - bug reports are more than welcome.
Cheers,
Al

Folks, updated namespace patch is on
ftp.math.psu.edu/pub/viro/namespaces-c-S4-pre6.gz
News:
* ported to 2.4.4-pre6
* fixes for d_flags races (already in -ac, hopefully will go into
the main tree soon)
* fixes for sync_inodes()/kill_super() races (submitted to Linus
and Alan, hopefully will go into the tree soon)
* killed low-memory deadlocks between {u,re,}mount and kswapd.
* further cleanup of fs/super.c
It works here. Please, help with testing. Patch had somewhat grown, but
new pieces are fixes for the bugs present in the main tree and these
fixes had been submitted for inclusion in 2.4, so hopefully it will
shrink again.
Cheers,
Al

New version of patch is on ftp.math.psu.edu/pub/viro/namespaces-d-S4-pre6.gz
* Fixed idiotic bug in do_add_mount() - the thing forgot
to pass error value back to the caller.
