the largest size of buffer cache block or the mapping of the buffer is bogus. When a mount with rsize=4096,wsize=4096 was done, f_iosize would be set to 4096. This resulted in corrupted directory data, since the buffer cache block size for directories is NFS_DIRBLKSIZ (8192). This patch fixes the code so that it always sets f_iosize to at least NFS_DIRBLKSIZ. Tested by: krichy@cflinux.hu PR: 177971 MFC after: 2 weeks
