Hi all, This is to check and confirm whether we have an API(or an internal implementation which can be exposed as API) to perform operations on an open file descriptor as a wrapper around existing fcntl() system call. We do have specific APIs for locks(glfs_posix_lock) and file descriptor duplication(glfs_dup) which are important among those operations listed as per man fcntl(2). At present we have a requirement(very recent) from Samba to set file descriptor flags through its VFS layer which would need a corresponding mechanism inside GlusterFS. Due to its absence, VFS module for GlusterFS inside Samba will have to workaround with the hack of creating fake local file descriptors outside GlusterFS. Thoughts and suggestions are welcome.
