    fs: Preserve error code in get_empty_filp(), part 2 · 39b65252
    Anatol Pomozov authored
    Allocating a file structure in function get_empty_filp() might fail because
    of several reasons:
     - not enough memory for file structures
     - operation is not allowed
     - user is over its limit
    Currently the function returns NULL in all cases and we loose the exact
    reason of the error. All callers of get_empty_filp() assume that the function
    can fail with ENFILE only.
    Return error through pointer. Change all callers to preserve this error code.
    [AV: cleaned up a bit, carved the get_empty_filp() part out into a separate commit
    (things remaining here deal with alloc_file()), removed pipe(2) behaviour change]
