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.
