FUSE RELEASE INTERFACE
|
|
======================
|
|
|
|
This header defines the two release() function overloads used for closing
|
|
open files. There are two variants because release can be initiated from
|
|
different contexts:
|
|
|
|
1. release(ctx, ffi) - Standard FUSE release callback
|
|
Called by libfuse when a file is closed. Extracts the FileInfo from
|
|
the fuse_file_info_t handle and calls the internal release function.
|
|
|
|
2. release(nodeid, fi) - Internal release function
|
|
Called internally when we need to release a file that failed to open
|
|
properly (e.g., in fuse_open.cpp when _open_fd fails after finding an
|
|
existing open). This allows the same cleanup logic to be used for both
|
|
normal closes and error cleanup.
|
|
|
|
The two-phase cleanup mechanism is implemented in fuse_release.cpp. See
|
|
that file for detailed documentation on the reference counting and
|
|
zombie state handling.
|
|
|
|
See commit 446e9a7b for the complete rationale behind this design.
