(Frodo) Added patches for 2.6.18 upto 2.6.22 kernels, including debian support

1 frodo 285 ***IMPORTANT***
2     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'.

8     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.
33    
34    
35     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
46 frodo 285 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.
57    
58    
59     Debian users
60     ------------
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.
64     Get it at the same place as this package (see Contact).
