fn forget(&mut self, _req: &Request<'_>, _ino: u64, _nlookup: u64)
Forget about an inode. The nlookup parameter indicates the number of lookups previously performed on this inode. If the filesystem implements inode lifetimes, it is recommended that inodes acquire a single reference on each lookup, and lose nlookup references on each forget. The filesystem may ignore forget calls, if the inodes don’t need to have a limited lifetime. On unmount it is not guaranteed, that all referenced inodes will receive a forget message. Read more

fn open(&mut self, _req: &Request<'_>, ino: u64, flags: i32, reply: ReplyOpen)
Open a file. Open flags (with the exception of O_CREAT, O_EXCL, O_NOCTTY and O_TRUNC) are available in flags. Filesystem may store an arbitrary file handle (pointer, index, etc) in fh, and use this in other all other file operations (read, write, flush, release, fsync). Filesystem may also implement stateless file I/O and not store anything in fh. There are also some flags (direct_io, keep_cache) which the filesystem may set, to change the way the file is opened.

Read data. Read should send exactly the number of bytes requested except on EOF or error, otherwise the rest of the data will be substituted with zeroes. An exception to this is when the file has been opened in ‘direct_io’ mode, in which case the return value of the read system call will reflect the return value of this operation. fh will contain the value set by the open method, or will be undefined if the open method didn’t set any value.

fn flush(
&mut self,
_req: &Request<'_>,
_ino: u64,
_fh: u64,
_lock_owner: u64,
reply: ReplyEmpty
)
Flush method. This is called on each close() of the opened file. Since file descriptors can be duplicated (dup, dup2, fork), for one open call there may be many flush calls. Filesystems shouldn’t assume that flush will always be called after some writes, or that if will be called at all. fh will contain the value set by the open method, or will be undefined if the open method didn’t set any value. NOTE: the name of the method is misleading, since (unlike fsync) the filesystem is not forced to flush pending writes. One reason to flush data, is if the filesystem wants to return write errors. If the filesystem supports file locking operations (setlk, getlk) it should remove all locks belonging to ‘lock_owner’. Read more

reply: ReplyEmpty
)
Release an open file. Release is called when there are no more references to an open file: all file descriptors are closed and all memory mappings are unmapped. For every open call there will be exactly one release call. The filesystem may reply with an error, but error values are not returned to close() or munmap() which triggered the release. fh will contain the value set by the open method, or will be undefined if the open method didn’t set any value. flags will contain the same flags as for open.

fn opendir(&mut self, _req: &Request<'_>, ino: u64, flags: i32, reply: ReplyOpen)
Open a directory. Filesystem may store an arbitrary file handle (pointer, index, etc) in fh, and use this in other all other directory stream operations (readdir, releasedir, fsyncdir). Filesystem may also implement stateless directory I/O and not store anything in fh, though that makes it impossible to implement standard conforming directory stream operations in case the contents of the directory can change between opendir and releasedir.

Create and open a file. If the file does not exist, first create it with the specified mode, and then open it. Open flags (with the exception of O_NOCTTY) are available in flags. Filesystem may store an arbitrary file handle (pointer, index, etc) in fh, and use this in other all other file operations (read, write, flush, release, fsync). There are also some flags (direct_io, keep_cache) which the filesystem may set, to change the way the file is opened. See fuse_file_info structure in <fuse_common.h> for more details. If this method is not implemented or under Linux kernel versions earlier than 2.6.15, the mknod() and open() methods will be called instead. Read more

Acquire, modify or release a POSIX file lock. For POSIX threads (NPTL) there’s a 1-1 relation between pid and owner, but otherwise this is not always the case. For checking lock ownership, ‘fi->owner’ must be used. The l_pid field in ‘struct flock’ should only be used to fill in this field in getlk(). Note: if the locking methods are not implemented, the kernel will still allow file locking to work locally. Hence these are only interesting for network filesystems and similar. Read more
