Prev: [PATCH 05/18] arm/omap: use generic_file_llseek in iommu_debug
Next: [PATCH 06/18] spufs: use llseek in all file operations
From: Arnd Bergmann on 7 Jul 2010 17:50
All file operations now have an explicit .llseek
operation pointer, so we can change the default
action for future code.

This makes changes the default from default_llseek
to no_llseek, which always returns -ESPIPE if
a user tries to seek on a file without a .llseek
operation.

The name of the default_llseek function remains
unchanged, if anyone thinks we should change it,
please speak up.
