| |
Hi,
I found out that O_DIRECT does not work correctly on 2.4 kernels compiled with the RH gcc-3.2.2-5 on RH9. It is working fine with kernels compiled with the RH gcc-2.96-113 on RH 7.3.
The sympton is that read() only returns zeroes (as data). No errors. It happens with several 2.4 kernels I have tried, including 2.4.21-ac1.
I don't know if this is a RH9 gcc specific bug or if it is a generic gcc3 problem. That's why I post here: to find out if more people have seen this.
I also filed a bug in RH's bugzilla. See this for more details:
