Subject[PATCH 4.19 035/191] Revert "block: ratelimit handle_bad_sector() message"
Date
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

This reverts commit f86b9bf6228bb334fe1addcd566a658ecbd08f7e which is
commit f4ac712e4fe009635344b9af5d890fe25fcc8c0d upstream.

Jari Ruusu writes:

Above change "block: ratelimit handle_bad_sector() message"
upstream commit f4ac712e4fe009635344b9af5d890fe25fcc8c0d
in 4.19.154 kernel is not completely OK.

Removing casts from arguments 4 and 5 produces these compile warnings:

...

For 64 bit systems it is only compile time cosmetic warning. For 32 bit
system + CONFIG_LBDAF=n it introduces bugs: output formats are "%llu" and
passed parameters are 32 bits. That is not OK.

Upstream kernels have hardcoded 64 bit sector_t. In older stable trees
sector_t can be either 64 or 32 bit. In other words, backport of above patch
needs to keep those original casts.

And Tetsuo Handa writes:
Indeed, commit f4ac712e4fe00963 ("block: ratelimit handle_bad_sector() message")
depends on commit 72deb455b5ec619f ("block: remove CONFIG_LBDAF") which was merged
into 5.2 kernel.

So let's revert it.
