* Enable writeback_cache and async_dio FUSE options
Fixes#7978
- Update mount_std.go to use EnableWriteback and EnableAsyncDio from go-fuse
- Add go.mod replace directive to use local go-fuse with capability support
- Remove temporary workaround that disabled these options
This enables proper FUSE kernel capability negotiation for writeback cache
and async direct I/O, improving performance for small writes and concurrent
direct I/O operations.
* Address PR review comments
- Remove redundant nil checks for writebackCache and asyncDio flags
- Update go.mod replace directive to use seaweedfs/go-fuse fork instead of local path
* Add TODO comment for go.mod replace directive
The replace directive must use a local path until seaweedfs/go-fuse#1 is merged.
After merge, this should be updated to use the proper version.
* Use seaweedfs/go-fuse v2.9.0 instead of local repository
Replace local path with seaweedfs/go-fuse v2.9.0 fork which includes
the writeback_cache and async_dio capability support.
* Use github.com/seaweedfs/go-fuse/v2 directly without replace directive
- Updated all imports to use github.com/seaweedfs/go-fuse/v2
- Removed replace directive from go.mod
- Using seaweedfs/go-fuse v2.0.0-20260106181308-87f90219ce09 which includes:
* writeback_cache and async_dio support
* Corrected module path
* Update to seaweedfs/go-fuse v2.9.1
Use v2.9.1 tag which includes the corrected module path
(github.com/seaweedfs/go-fuse/v2) along with writeback_cache
and async_dio support.
mount: remove unused isEarlyTerminated variable
The variable was redundant because when processEachEntryFn returns false,
we immediately return fuse.OK, so the check was always false.

* mount: add mutex to DirectoryHandle to fix race condition
When using Ganesha NFS on top of FUSE mount, ls operations would hang
forever on directories with hundreds of files. This was caused by a
race condition in DirectoryHandle where multiple concurrent readdir
operations could modify shared state (entryStream, entryStreamOffset,
isFinished) without synchronization.
The fix adds a mutex to DirectoryHandle and holds it for the entire
duration of doReadDirectory. This serializes concurrent readdir calls
on the same handle, which is the correct behavior for a directory
handle and fixes the race condition.
Key changes:
- Added sync.Mutex to DirectoryHandle struct
- Lock the mutex at the start of doReadDirectory
- This ensures thread-safe access to entryStream and other state
The lock is per-handle (not global), so different directories can
still be listed concurrently. Only concurrent operations on the
same directory handle are serialized.
