Subject: bfs: replace get_zeroed_page() with kzalloc()
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=c1fe8d334f93ebdba07c8a28c07fbd619e673633;p=thirdparty%2Fkernel%2Flinux.git

bfs: replace get_zeroed_page() with kzalloc()

bfs_dump_imap() allocates temporary buffer with get_zeroed_page().

kmalloc() is a better API for such use and it also provides better
scalability and more debugging possibilities.

Replace use of get_zeroed_page() with kzalloc().
