Hi,
When testing file creation performance we noticed that sometimes ext3
getdents64(2) lists some files twice. For instance after creating
filesnames from 1 to 1000000 in an empty directory:
find | grep ./976253
./976253
./976253
This is 100% reproducible. Kernel is 2.6.25.5, x86_64.
Sorry if this was already known and fixed (couldn't find relevant info in
the archives, changelogs).
Regards,
Szaka

2.6.28 and newer kernels should have this bug fixed.
