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. Signed-off-by:

While checkpointing we have to check that our transaction still is in the checkpoint list *and* (not or) that it's not just a different transaction with the same address. Signed-off-by:

Fix race in setting bitfields of fuse_conn. Spotted by Andrew Morton. The two fields ->connected and ->mounted were always changed with the fuse_lock held. But other bitfields in the same structure were changed without the lock. In theory this could lead to losing the assignment of even the ones under lock. The chosen solution is to change these two fields to be a full unsigned type. The other bitfields aren't "important" enough to warrant the extra complexity of full locking or changing them to bitops. For all bitfields document why they are safe wrt. concurrent assignments. Also make the initialization of the 'num_waiting' atomic counter explicit. Signed-off-by:

This patch changes fuse_readpages() to send READ requests asynchronously. This makes it possible for userspace filesystems to utilize the kernel readahead logic instead of having to implement their own (resulting in double caching). Signed-off-by:

Add a separate function for filling in the READ request. This will make it possible to send asynchronous READ requests as well as synchronous ones. Signed-off-by:

Add possibility for requests to run asynchronously and call an 'end' callback when finished. With this, the special handling of the INIT and RELEASE requests can be cleaned up too. Signed-off-by:

Add ability to abort a filesystem connection. With the introduction of asynchronous reads, the ability to interrupt any request is not enough to dissolve deadlocks, since now waiting for the request completion (page unlocked) is independent of the actual request, so in a deadlock all threads will be uninterruptible. The solution is to make it possible to abort all requests, even those currently undergoing I/O to/from userspace. The natural interface for this is 'mount -f mountpoint', but that only works as long as the filesystem is attached. So also add an 'abort' attribute to the sysfs view of the connection.

This patch adds the 'waiting' attribute which indicates how many filesystem requests are currently waiting to be completed. A non-zero value without any filesystem activity indicates a hung or deadlocked filesystem. Signed-off-by:

Kobjectify fuse_conn, and make it visible under /sys/fs/fuse/connections. Lacking any natural naming, connections are numbered. This patch doesn't add any attributes, just the infrastructure. Signed-off-by:
-
Miklos Szeredi authored
The ->connected flag for a fuse_conn object previously only indicated whether the device file for this connection is currently open or not. Change it's meaning so that it indicates whether the connection is active or not: now either umount or device release will clear the flag. The separate ->mounted flag is still needed for handling background requests. Signed-off-by:

The state of request was made up of 2 bitfields (->sent and ->finished) and of the fact that the request was on a list or not. Unify this into a single state field. Signed-off-by:

This function used the request object after decrementing its reference count and releasing the lock. This could in theory lead to all sorts of problems. Fix and simplify at the same time. Signed-off-by:

fuse_copy_finish() must be called before request_end(), since the later might sleep, and no sleeping is allowed between fuse_copy_one() and fuse_copy_finish() because of kmap_atomic()/kunmap_atomic() used in them. Signed-off-by:

Mark a few VFS functions as mandatory inline (based on Al Viro's request); these must be inline due to stack usage issues during a recursive loop that happens during the recursive symlink resolution (symlink to a symlink to a symlink ..) This patch at this point does not change behavior and is for documentation purposes only (but this changes later in the series) Signed-off-by:

fs/quota_v2.c can, under some conditions, issue a kernel message that says, in totality, 'failed read'. This patch does the following: 1) Gives a hint who issued the error message, so people reading the logs don't have to go grepping the entire kernel tree (with 11 false positives). 2) Say what amount of data we expected, and actually got.

Anything that writes into a tmpfs filesystem is liable to disproportionately decrease the available memory on a particular node. Since there's no telling what sort of application (e.g. dd/cp/cat) might be dropping large files there, this lets the admin choose the appropriate default behavior for their site's situation. Introduce a tmpfs mount option which allows specifying a memory policy and a second option to specify the nodelist for that policy. With the default policy, tmpfs will behave as it does today. This patch adds support for preferred, bind, and interleave policies. The default policy will cause pages to be added to tmpfs files on the node which is doing the writing. Some jobs expect a single process to create and manage the tmpfs files. This results in a node which has a significantly reduced number of free pages. With this patch, the administrator can specify the policy and nodes for that policy where they would prefer allocations. This patch was originally written by Brent Casavant and Hugh Dickins. I added support for the bind and preferred policies and the mpol_nodelist mount option. Signed-off-by:
