Subject: [PATCH RFC 0/5] Add threading support to e2fsprogs

This patch set adds the infrastructure to support threading to
libext2fs.  It makes the unix_io I/O Manager thread-aware.  Wang's
parallel bitmap code has been adapted to use the new threading
infrastructure.

The code has been tested with TSAN and ASAN built into gcc 10.2:

    configure 'CFLAGS=-g -fsanitize=thread' 'LDFLAGS=-fsanitize=thread'
    make clean ; make -j16 ; make -j16 check
    configure 'CFLAGS=-g -fsanitize=address' 'LDFLAGS=-fsanitize=address'
    make clean ; make -j16 ; make -j16 check

As I needed to excerpt out some of the changes to generated patches in
"Add configure and build support for the pthreads", the full patch
series can be found in git:

git fetch https://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git pthreads


Theodore Ts'o (4):
  Add configure and build support for the pthreads library
  libext2fs: add threading support to the I/O manager abstraction
  libext2fs: allow the unix_io manager's cache to be disabled and
    re-enabled
  Enable threaded support for e2fsprogs' applications.

Wang Shilong (1):
  ext2fs: parallel bitmap loading
