Subject: e2fsck: propagate number of threads
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3f56676f4daa7379dbd868a4114910f20d49527d;p=thirdparty%2Fe2fsprogs.git

e2fsck: propagate number of threads

Sometimes, such as in orphan_inode case, e2fsck_pass1
is called after reading the block bitmaps. This results in
reading the block bitmap sequentially and multithreading
only gets kicked in later. Fix the thread count earlier
while setting up the file system.
