Subject: [PATCH] libext2fs: Fix fsync(2) detection
|
||
|
|
References: bsc#1038194
|
||
|
|
|
||
|
|
For some reason lib/config.h.in was missing a definition of HAVE_FSYNC
|
||
|
|
and as a result lib/config.h never had HAVE_FSYNC defined. As a result
|
||
|
|
we never called fsync(2) for example from
|
||
|
|
lib/ext2fs/unix_io.c:unix_flush() when we finished creating filesystem
|
||
|
|
and could miss IO errors happening during creating of the filesystem.
|
||
|
|
Test generic/405 exposes this problem.
|
||
|
|
|
||
|
|
Fix the problem by defining HAVE_FSYNC in lib/config.h.in.
