* [PATCH] v9fs: remove additional buffer allocation from v9fs_file_read and ↵Latchesar Ionkov2005-10-111-81/+33
| | | | | | | | | | | | | | | | | 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.

* [PATCH] v9fs: fix races in fid allocationLatchesar Ionkov2005-09-281-60/+28
| | | | | | | | | | | | | | | | | | | | Fid management cleanup. The patch attempts to fix the races in dentry's fid management. Dentries don't keep the opened fids anymore, they are moved to the file structs. Ideally there should be no more than one fid with fidcreate equal to zero in the dentry's list of fids. v9fs_fid_create initializes the important fields (fid, fidcreated) before v9fs_fid is added to the list. v9fs_fid_lookup returns only fids that are not created by v9fs_create. v9fs_fid_get_created returns the fid created by the same process by v9fs_create (if any) and removes it from dentry's list Signed-off-by: Latchesar Ionkov <lucho@ionkov.net> Cc: Eric Van Hensbergen <ericvh@gmail.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
