| Summary | 0004941: In fat_fus.c, handle files > 2GB better | ||||
| Description | In fat_fus.c, handle files > 2GB better In fat_size(), function file_fat_read() is called. This returns either the size of the file or a negative error code. The previous comparison with < 0 has problems if the file size exceeds 2GB. Then the size has bit 31 set and is interpreted as a negative value and hence as an error value. Use IS_ERR_VALUE() instead, then only a few very large files with nearly 4GB will have problems. Remark: The function file_fat_read() is only called in very few places. Maybe we can remove it completely and use file_fat_read_at() instead which has a separate pointer for the size and does not mix it up with the return value. | ||||
