+ *

+ * @close:
+ *      Notify backend that pstore has finished a full read of backend
+ *      records. Always preceded by an @open call and one or more @read
+ *      calls.
+ *
+ *      @psi:   in: pointer to the struct pstore_info for the backend
+ *
+ *      Returns 0 on success, and non-zero on error. (Though pstore will
+ *      ignore the error.)
+ *
+ * @read:
+ *      Read next available backend record. Called after a successful
+ *      @open.
+ *
+ *      @record:
+ *              pointer to record to populate. @buf should be allocated
+ *              by the backend and filled. At least @type and @id should
+ *              be populated, since these are used when creating pstorefs
+ *              file names.
+ *
+ *      Returns record size on success, zero when no more records are
+ *      available, or negative on error.
+ *
+ * @write:
+ *      A newly generated record needs to be written to backend storage.
+ *
+ *      @record:
+ *              pointer to record metadata. When @type is PSTORE_TYPE_DMESG,
+ *              @buf will be pointing to the preallocated @psi.buf, since
+ *              memory allocation may be broken during an Oops. Regardless,
+ *              @buf must be proccesed or copied before returning. The
+ *              backend is also expected to write @id with something that
+ 8              can help identify this record to a future @erase callback.
+ *
+ *      Returns 0 on success, and non-zero on error.
+ *
+ * @write_user:
+ *      Perform a frontend write to a backend record, using a specified
+ *      buffer that is coming directly from userspace, instead of the
+ *      @record @buf.
+ *
+ *      @record:        pointer to record metadata.
+ *      @buf:           pointer to userspace contents to write to backend
+ *
+ *      Returns 0 on success, and non-zero on error.
+ *
+ * @erase:
+ *      Delete a record from backend storage.  Different backends
+ *      identify records differently, so entire original record is
+ *      passed back to assist in identification of what the backend
+ *      should remove from storage.

+ * Architectures should provide two primitives (raw_copy_{to,from}_user())
+ * and get rid of their private instances of copy_{to,from}_user() and
+ * __copy_{to,from}_user{,_inatomic}().
+ *
+ * raw_copy_{to,from}_user(to, from, size) should copy up to size bytes and
+ * return the amount left to copy.  They should assume that access_ok() has
+ * already been checked (and succeeded); they should *not* zero-pad anything.
+ * No KASAN or object size checks either - those belong here.
+ *
+ * Both of these functions should attempt to copy size bytes starting at from
+ * into the area starting at to.  They must not fetch or store anything
+ * outside of those areas.  Return value must be between 0 (everything
+ * copied successfully) and size (nothing copied).
+ *
+ * If raw_copy_{to,from}_user(to, from, size) returns N, size - N bytes starting
+ * at to must become equal to the bytes fetched from the corresponding area
+ * starting at from.  All data past to + size - N must be left unmodified.
+ *
+ * If copying succeeds, the return value must be 0.  If some data cannot be
+ * fetched, it is permitted to copy less than had been fetched; the only
+ * hard requirement is that not storing anything at all (i.e. returning size)
+ * should happen only when nothing could be copied.  In other words, you don't
+ * have to squeeze as much as possible - it is allowed, but not necessary.
+ *
+ * For raw_copy_from_user() to always points to kernel memory and no faults
+ * on store should happen.  Interpretation of from is affected by set_fs().
+ * For raw_copy_to_user() it's the other way round.
+ *
+ * Both can be inlined - it's up to architectures whether it wants to bother
+ * with that.  They should not be used directly; they are used to implement
+ * the 6 functions (copy_{to,from}_user(), __copy_{to,from}_user_inatomic())
+ * that are used instead.  Out of those, __... ones are inlined.  Plain
+ * copy_{to,from}_user() might or might not be inlined.  If you want them
+ * inlined, have asm/uaccess.h define INLINE_COPY_{TO,FROM}_USER.
+ *
+ * NOTE: only copy_from_user() zero-pads the destination in case of short copy.
+ * Neither __copy_from_user() nor __copy_from_user_inatomic() zero anything
+ * at all; their callers absolutely must check the return value.
+ *
+ * Biarch ones should also provide raw_copy_in_user() - similar to the above,
+ * but both source and destination are __user pointers (affected by set_fs()
+ * as usual) and both source and destination can trigger faults.
