* 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.
* Fix: prevent panic when swap file creation fails
* weed mount: fix race condition in swap file initialization
Ensure thread-safe access to sf.file and other state in NewSwapFileChunk
and FreeResource by using sf.chunkTrackingLock consistently. Also
set sf.file to nil after closing to prevent reuse.
* weed mount: improve swap directory creation logic
- Check error for os.MkdirAll and log it if it fails.
- Use 0700 permissions for the swap directory for better security.
- Improve error logging context.
* weed mount: add unit tests for swap file creation
Add tests to verify:
- Concurrent initialization of the swap file.
- Correct directory permissions (0700).
- Automatic directory recreation if deleted.
* weed mount: fix thread-safety in swap file unit tests
Use atomic.Uint32 to track failures within goroutines in
TestSwapFile_NewSwapFileChunk_Concurrent to avoid unsafe calls to
t.Errorf from multiple goroutines.
* weed mount: simplify swap file creation logic
Refactor the directory check and retry logic for better readability and
to avoid re-using the main error variable for directory creation errors.
Remove redundant error logging.
* weed mount: improve error checking in swap file tests
Explicitly check if NewSwapFileChunk returns nil to provide more
informative failures.
* weed mount: update DirtyPages interface to return error
Propagate errors from SaveDataAt when swap file creation fails. This
prevents potential panics in the write path.
* weed mount: handle AddPage errors in write paths
Update ChunkedDirtyPages and PageWriter to propagate errors and update
WFS.Write and WFS.CopyFileRange to return fuse.EIO on failure.
* weed mount: update swap directory creation error message
Change "recreate" to "create/recreate" to better reflect that this path
is also taken during the initial creation of the swap directory.

Fixes:
1. set start and stop offset for the value object
2. clone the value object
3. use pointer instead of copy-by-value when passing to interval.Value
4. use insert interval since adding chunk could be out of order
