Subject: ext3: pass custom EOF to generic_file_llseek_size()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=de9b9422026357c878a9fa3714936be0e1388e9c;p=linux-beck.git

ext3: pass custom EOF to generic_file_llseek_size()

Use the new custom EOF argument to generic_file_llseek_size so
that SEEK_END will go to the max hash value for htree dirs
in ext3 rather than to i_size_read()
