Detailed Description

Fop state machine for IO operations

See also: fom; DLD of Bulk Server

FOP state machines for various IO operations like

Readv
Writev

Note: Naming convention: For operation xyz, the FOP is named as m0_fop_xyz, its corresponding reply FOP is named as m0_fop_xyz_rep and FOM is named as m0_fom_xyz. For each FOM type, its corresponding create, state and fini methods are named as m0_fom_xyz_create, m0_fom_xyz_state, m0_fom_xyz_fini respectively.

static

Copy aligned bufvec segments addresses from net buffer to stob bufvec. STOB I/O expects exact same number of bufvec as index vecs for I/O request. This function copies segment from network buffer with size same as ivec_count.

Parameters

fom	file operation machine instance.
obuf	pointer to bufvec from stobio object.
ibuf	pointer to bufve from network buffer from buffer pool.
ivec_count	number of vectors for stob I/O request.
bshift	shift value for current stob to align bufvecs.

Precondition: obuf != NULL; ibuf != NULL
