Module Name: src
Committed By: manu
Date: Thu Aug 26 13:29:02 UTC 2010
Modified Files:
src/lib/libperfuse: ops.c perfuse_if.h perfuse_priv.h subr.c
src/usr.sbin/perfused: debug.c perfused.8 perfused.c
Log Message:
- open the file before doing fsync: glusterfs wants that.
- Automatically call fsync on close for files. If we just close, fsync
will come later and we will have to reopen
- Add a PND_DIRTY flag to keep track of files that really need a sync.
perfuse_node_fsync only calls the FUSE fsync method if there are data
to push.
- Add a PND_OPEN flag to keep track of open files. Checking non NULL
fh is not enough, as some filesystems will always set fh to 0.
- Add a sync diagnostic flag, to watch fsync and dirty flag activity.
Make the fh diagnostic flag more verbose
- Send the fh in setattr (it was hardcoded to 0)
I am now able to build libperfuse in a glusterfs mounted filesystem. Yeah!
