Aravind Srinivasan	8e8aa27e1b	s3: Fix streams enumeration bug in OneFS implementation ... Previously, we didn’t call SMB_VFS_OPEN_DIR from the streams module, instead we called fdopendir(). As a result we failed to populate the dir_state list in the readdirplus module. So when we tried to view the stream data, we will always returned NULL. To solve this I separated onefs_opendir() and the initialization of the dir_state list. This is done by introducing a new utility function “onefs_rdp_add_dir_state()”, which initializes the dir_state structure and adds it to the dir_state list. This function is called from the streams module before calling readdir().	2009-02-18 20:49:31 -08:00
Steven Danneman	11f60a62a1	s3: OneFS bulk directory enumeration support ... OneFS provides the bulk directory enumeration syscall readdirplus(). This syscall has the same semantics as the NFSv3 READDIRPLUS command, returning a batch of directory entries with prefetched stat information via one syscall. This commit wraps the readdirplus() call in the existing POSIX readdir/seekdir VFS interface. By default a batch of 128 directory entries are optimistically read from the kernel into a global cache, and fed to iterative calls of VFS_OP_READDIR. The global buffers could be avoided in the future by hanging connection specific buffers off the conn struct. Added new parameter "onefs:use readdirplus" which toggles usage of this code on or off.	2009-02-09 23:56:17 -08:00
