343e8df31e Add puffs_framev_enqueue_waitevent, which waits for read/write/error 
events from an i/o descriptor.  It yields until an event happens
and continues execution when the event loop notices the event has
happened.

f2825a0ae8 Don't float puffs_kargs needlessly around after mount, saves 
a couple k of memory (and there was much rejoycing!)

044229479a wizd reminded me that if I provide the synopsis for puffs_node_seek(), 
I would do well to also describe what it does.  so make it so.

2f6b69c368 Use ioctl(PUFFSREQSIZEOP) instead of mount(MNT_GETARGS) to fetch 
the maximum request size after mount.  Calling mount(MNT_GETARGS)
from the file server is currently not kosher, as it vrele()s the
root vnode, potentially causing an inactive, which the file server
cannot handle while it itself is inactive in the kernel (deadlock).

0666faeea3 Add new 'data_len' parameter to mount system call. 
Add an additional call with MNT_GETARGS to retrieve the modified
information instead of relying on the kernel code abusing the mount
interface during mount.

8c9c68dbc2 Make puffs_framebuf better suited from environments with multiple sources: 
* in addition add/remove, allow enable/disable, which can be used
  to control events for descriptors without having to remove all the
  data associated with them
* add directsend/receive, which can be used to pass the same buffer
  from the caller to read/writeframe and back again
* add flags to enqueue functions and allow urgent buffers to be
  processed as the next PDU

0f53ecfb54 fold in common code for node creation. no functional change. 2007-06-25 07:52:01 +00:00
pooka
c3942902c4 Since we locate in-memory nodes based on the inode number, stat a 
file always after creation to cache the inode number given by the
backend file system.  Otherwise we would not find a newly created
node from incore and create another one.  In practise this was
pretty well hidden by the kernel name cache.

53a4105885 Actually, keep PUFFS_KFLAG_NOCACHE and -o cache around as shorthand 
to neither page- nor namecache.

5662e7f720 PUFFS_KFLAG_NOCACHE became two, so introduce the command line options 
-o nonamecache and -o nopagecache and adapt file systems where necessary.

 2007-06-24 18:16:36 +00:00
pooka
564336f084 Introduce puffs_pn_remove() to signal that a node has been deleted 
and destroyed, but not yet reclaimed.  This prevents puffs_pn_nodewalk()
from returning stale entries.  Make nullfs use this (some file
systems are a bit too happy with recycling inode numbers).

86e63e7e27 don't return errno from a function which returns an fd - there's 
a "little" room for confusion.  instead, return -1 and let the
caller grab errno.

f8326bf98e Move puffs to a two clause license where it already isn't so. And 
as agc pointed out, even files with the third clause were already
effectively two clause because of a slight bug in the language...
