Subject: Add --enable-test-io-debug configure option which causes e2fsck and
X-Git-Tag: E2FSPROGS-1_34-WIP-0521~25
X-Git-Url: https://git.whamcloud.com/?a=commitdiff_plain;h=2a29f1354f793557fa1829c9e85e74586e2907db;p=tools%2Fe2fsprogs.git

Add --enable-test-io-debug configure option which causes e2fsck and
tune2fs to use the test I/O manager.

The test I/O manager has been changed to not do anything extra by
default, unless the TEST_IO_FLAGS and/or TEST_IO_BLOCK environment
variables are set, which controls what I/O operations are logged and
a block number to watch, respectively.  The log messages are sent to
stderr by default, unless a filename is specified via the
TEST_IO_LOGFILE environment variable.
