Subject: do_generic_mapping_read abuse in gfs2
Date: Sat, 28 Jul 2007 19:42:38 +0200 [thread overview]
Message-ID: <20070728174238.GA5805@lst.de> (raw)
I was looking into cleaning up the the read actor mess now that sendfile
uses splice and notices gfs2 now uses do_generic_mapping_read.
The use is rather odd because it's used for reading small structures
from kernelspace and thus doesn't actually needs the fullblown
do_generic_mapping_read at all. Any chance you could switch it to
a simple read_cache_page() so we can kill do_generic_mapping_read?
