Re: generic_file_read()



Usually file system operations that begin with "generic_" are used by
most "normal" file systems.  "generic_file_read()" will perform a read
operation, and "generic_file_open()" will perform an open operation.
These generic functions are usually used by block-based file systems
that do not need to do anything special for a given operation.  Rather
than have several file system write the same code, they were put into
the VFS.

I took a quick glance at the kiocb structure, and it looks like it is
used for asynchronous I/O.

If you want more specific answers, please ask more specific questions.
