Subject: block: remove redundant kill_bdev() call in set_blocksize()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d4d78dd43cecaeaadb24e78927a4d6fda7d1f1d9;p=thirdparty%2Flinux.git

block: remove redundant kill_bdev() call in set_blocksize()

The second kill_bdev() call in set_blocksize() is redundant as the first
call already clears all buffers and pagecache, and locks prevent new
pagecache creation between the calls.
