This package is renamed kernel-patch-fat-epoc. The old package, called |
| 3 |
|
|
kernel-patch-fat-old, should not be used anymore. The mount option for |
| 4 |
|
|
2.6 kernels, previously called `oldfat' is renamed `epoc'. |

Introduction |
| 9 |
|
|
------------ |
| 10 |
|
|
|
| 11 |
|
|
In the FAT standard the end of the directory file index is marked by 00. |
| 12 |
|
|
All entries after it should be ignored. The current FAT implementation |
| 13 |
|
|
ignores such marked entries, but continues scanning the directory. This |
| 14 |
|
|
is good enough for most FAT implementations, because they also mark all |
| 15 |
|
|
remaining entries after the last with a 00 byte. |
| 16 |
|
|
|
| 17 |
|
|
The filesystem implementation of EPOC 5(MX) (and probably of newer versions |
| 18 |
|
|
of EPOC) does not clear old entries after the end of the directory file |
| 19 |
|
|
index. This means that without this patch, Linux will show old previously |
| 20 |
|
|
deleted or even never assigned entries. |
| 21 |
|
|
|
| 22 |
|
|
This patch will affect FAT-based filesystems. Examples are filesystems |
| 23 |
|
|
of the type `msdos' or `vfat'. |
| 24 |
|
|
|
| 25 |
|
|
The patch for 2.6 kernels is not active, unless you specify the epoc mount |
| 26 |
|
|
option. For example: |
| 27 |
|
|
mount /dev/sda1 /mnt/psion-epoc -t vfat -o epoc |
| 28 |
|
|
|
| 29 |
|
|
The patch for 2.4 kernels has some known issues. All FAT-based partitions |
| 30 |
|
|
will use the new policy; there is no mount option. In most cases it should |
| 31 |
|
|
work well enough; if you want to be completely safe, mount FAT-based |
| 32 |
|
|
partitions read-only. |

Applying the patches |
| 36 |
|
|
-------------------- |
| 37 |
|
|
|
| 38 |
|
|
There are several patches included in this package: |
| 39 |
|
|
fat-epoc-2.4.20.diff For any 2.4 kernel |
| 40 |
|
|
fat-epoc-2.6.0.diff For 2.6.0 to 2.6.10 kernels |
| 41 |
|
|
fat-epoc-2.6.11.diff For 2.6.11 kernels |
| 42 |
frodo |
298 |
fat-epoc-2.6.12.diff For 2.6.12, 2.6.13 and 2.6.14 kernels |
| 43 |
frodo |
303 |
fat-epoc-2.6.15.diff For 2.6.15 to 2.6.18 kernels |
| 44 |
|
|
fat-epoc-2.6.19.diff For 2.6.19, 2.6.20 and 2.6.21 kernels |
| 45 |
|
|
fat-epoc-2.6.22.diff For 2.6.22 and newer kernels |

Choose the patch that fits your kernel. |
| 47 |
|
|
|
| 48 |
|
|
Now go to the kernel base directory (often called /usr/src/linux) and issue |
| 49 |
|
|
the following command: |
| 50 |
|
|
patch -p1 -E < PATCHFILE |
| 51 |
|
|
If you want to see what will happen without applying the patch, try: |
| 52 |
|
|
patch -p1 -E --dry-run < PATCHFILE |
| 53 |
|
|
You may get a few messages about offsets; this is normal. But no fuzzy matches |
| 54 |
|
|
should be reported, and certainly no rejects. |
| 55 |
|
|
|
| 56 |
|
|
After this compile your kernel as usual. |

Debian users |

|
|
------------ |
| 61 |
|
|
|
| 62 |
|
|
There is also a Debian version of this package. If you install it, and compile |
| 63 |
|
|
your kernel "the Debian way", the right patch will be applied automatically. |
