|
|
work correctly when copying read-only files.
|
|
|
|

|
|
|

|
- Some bugfixes
|
|
|
|
============================================================================
|
|
|
|
What is new in 2.3
|
|
|
|
- Add new directory related operations: opendir(), readdir(),
|
|
releasedir() and fsyncdir()
|
|
|
|
- Add init() and destroy() operations which are called before the
|
|
event loop is started and after it has exited
|
|
|
|
- Update kernel ABI so that on dual architectures (e.g. AMD64) 32bit
|
|
binaries work under a 64bit kernel
|
|
|
|
- Bugfixes
|
|
|
|
============================================================================
|
|
|
|
What is new in 2.2
|
|
|
|
Userspace changes:
|
|
|
|
- Add fuse_file_info structure to file operations, this allows the
|
|
filesystem to return a file handle in open() which is passed to
|
|
read(), write(), flush(), fsync() and release().
|
|
|
|
- Add source compatibility with 2.1 and 1.4 releases
|
|
|
|
- Binary compatibility with 2.1 release is retained
|
|
|
|
Kernel changes:
|
|
|
|
- Make requests interruptible. This prevents the filesystem to go
|
|
into an unbreakable deadlock with itself.
|
|
|
|
- Make readpages() synchronous. Asynchronous requests are deadlock
|
|
prone, since they cannot be interrupted (see above)
|
|
|
|
- Remove shared-writeable mapping support, which could deadlock the
|
|
machine
|
|
|
|
- Remove INVALIDATE userspace initiated request
|
|
|
|
- Update ABI to be independent of sizeof(long), so dual-size archs
|
|
don't cause problems
|
|
|
|
- Remove /sys/fs/fuse/version. Version checking is now done through
|
|
the fuse device
|
|
|
|
- Replace directory reading method on the kernel interface. Instead
|
|
of passing an open file descriptor to the kernel, send data through
|
|
the FUSE device, like all other operations.
