Version 0.40 (August 13, 2001) |
| |
- Concurrent readers and writers are now supported correctly (data is |
| |
not consumed when it is first read, as it was in previous |
| |
versions). |
| |
- emlog's ring buffers now allocated using vmalloc instead of kmalloc |
| |
to avoid locking large blocks of contiguous physical memory. |
| |
- Added MODVERSIONS support |
| |
- Added the 'nbcat' utility - similar to cat, but does not block at |
| |
the end of the data. |
| |
- Bug fix: both device number and inode number are now stored |
| |
internally (instead of only the inode number). This prevents the |
| |
(unlikely) possibility that emlogs on different filesystems might |
| |
share a single buffer. |
