Subject: [PATCH] v9fs: remove additional buffer allocation from v9fs_file_read and v9fs_file_write
X-Git-Tag: v2.6.14-rc5~84
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=19cba8abd6ca09527c194864ae651db65cbacfe1;p=pandora-kernel.git

[PATCH] v9fs: remove additional buffer allocation from v9fs_file_read and v9fs_file_write

v9fs_file_read and v9fs_file_write use kmalloc to allocate buffers as big
as the data buffer received as parameter.  kmalloc cannot be used to
allocate buffers bigger than 128K, so reading/writing data in chunks bigger
than 128k fails.

This patch reorganizes v9fs_file_read and v9fs_file_write to allocate only
buffers as big as the maximum data that can be sent in one 9P message.
