Revision c227e69028473c7c7994a9b0a2cc0034f3f7e0fe authored by Arnd Bergmann on 22 September 2010, 20:04:54 UTC, committed by Linus Torvalds on 23 September 2010, 00:22:38 UTC
Commit 73296bc611 ("procfs: Use generic_file_llseek in /proc/vmcore")
broke seeking on /proc/vmcore. This changes it back to use default_llseek
in order to restore the original behaviour.
The problem with generic_file_llseek is that it only allows seeks up to
inode->i_sb->s_maxbytes, which is zero on procfs and some other virtual
file systems. We should merge generic_file_llseek and default_llseek some
day and clean this up in a proper way, but for 2.6.35/36, reverting vmcore
is the safer solution.
