d_path: make 'prepend()' fill up the buffer exactly on overflow

2021-09-02T17:07:29+00:00

Instead of just marking the buffer as having overflowed, fill it up as much as we can. That will allow the overflow case to then return whatever truncated result if it wants to. Cc: Al Viro Signed-off-by: Linus Torvalds

d_path: introduce struct prepend_buffer

2021-05-19T00:14:53+00:00

We've a lot of places where we have pairs of form (pointer to end of buffer, amount of space left in front of that). These sit in pairs of variables located next to each other and usually passed by reference. Turn those into instances of new type (struct prepend_buffer) and pass reference to the pair instead of pairs of references to its fields. Declared and initialized by DECLARE_BUFFER(name, buf, buflen). extract_string(prepend_buffer) returns the buffer contents if no overflow has happened, ERR_PTR(ENAMETOOLONG) otherwise. All places where we used to have that boilerplate converted to use of that helper. Signed-off-by: Al Viro
