coverity found two needless checks in vfs_inode.c (cid #1165 and #1164) In both cases inode is always NULL when we goto error; either because it is still initialized to NULL or is set to NULL explicitly. This patch simply removes these checks to save some code.

Multiple races can happen when v9fs is interrupted by a signal and Tflush message is sent to the server. After v9fs sends Tflush it doesn't wait until it receives Rflush, and possibly the response of the original message. This behavior may confuse v9fs what fids are allocated by the file server. This patch fixes the races and the fid allocation.

If a file is not found in v9fs_vfs_lookup, the function creates negative dentry, but doesn't assign any dentry ops. This leaves the negative entry in the cache (there is no d_delete to mark it for removal). If the file is created outside of the mounted v9fs filesystem, the file shows up in the directory with weird permissions. This patch assigns the default v9fs dentry ops to the negative dentry.

In order to assure atomic create+open v9fs stores the open fid produced by v9fs_vfs_create in the dentry, from where v9fs_file_open retrieves it and associates it with the open file. This patch modifies v9fs to use nameidata.intent.open values to do the atomic create+open.

v9fs mmap support was originally removed from v9fs at Al Viro's request, but recently there have been requests from folks who want readpage functionality (primarily to enable execution of files mounted via 9P). This patch adds readpage support (but not writepage which contained most of the objectionable code). It passes fsx-linux (and other regressions) so it should be relatively safe.

- remove unnecessary -ENOMEM assignments - return correct value when buf_check_size for second time in a buffer - handle failures when create_workqueue and kthread_create are called - use kzalloc instead of kmalloc/memset 0 - v9fs_str_copy and v9fs_str_compare were buggy, were used only in one place, correct the logic and move it to the place it is used.

v9fs_create doesn't manage correctly the fids when it is called to create a directory.. The fid created by the create 9P call (newfid) and the one created by walking to already created file (wfidno) are not used consistently. This patch cleans up the usage of newfid and wfidno.

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>

v9fs_vfs_readlink allocates space for the link using __getname and errorneously uses strlen on the newly allocated buffer to check if the buffer passed by the user is bigger than the one returned by __getname. The patch replaces the strlen usage to PATH_MAX, which is the actual size of the buffers returned by __getname.

LANL reported some issues with random crashes during mount of legacy protocol servers (9P2000 versus 9P2000.u) -- crash was always happening in readlink (which should never happen in legacy mode). Added some sanity conditionals to the get_inode code which should prevent the errors LANL was seeing. Code tested benign through regression.
