has been updated twice: Once to apply to squashfs 4.4, commit

Subject: [PATCH] mksquashfs 4K aligns the files inside the squashfs image
|
||||
|
||||
Files inside a squashfs image are not necessarily 4k (4096)
|
||||
aligned. This patch starts each file in a 4k aligned address and pads
|
||||
zero to the end of the file until it reaches the next 4k aligned
|
||||
address. This will not change the size of the compressed
|
||||
blocks (especially the last one) and hence it will not change how the
|
||||
files are being loaded in kernel or unsquashfs. However on average this
|
||||
increases the size of the squashfs image which can be calculated by the
|
||||
following formula:
|
||||
|
||||
increased_size = (number_of_unfragmented_files_in_image + number of fragments) * 2048
|
||||
|
||||
The 4k alignment can be enabled by flag '-4k-align'
