[fuse-devel] locking in multi-threaded filesystems

[Scott F. <sf...@br...>]

Are there any requirements for locking when a filesystem is running in
multi-threaded mode, or does the FUSE library handle its own
synchronization?  I ask because I'm faced with a very annoying bug in
my filesystem that's causing a segmentation fault only in
multi-threaded mode and the issue only manifests itself after about a
60 or so concurrent 'ls' commands have been issued on a directory with
20,000 sub-directories.

Also, is there ever a time when you'd need to use the offset parameter
of the filler function passed to readdir()?  Is it always safe to use
0 as the offset?

Thanks,
Scott
