I've restricted atomic_open to only operate on regular files, although I still don't understand why atomic_open should not be possible also for directories on GFS2. That can always be added in later though, if it makes sense. The ->atomic_open function can be passed negative dentries, which in most cases means either ENOENT (->lookup) or a call to d_instantiate (->create). In the GFS2 case though, we need to actually perform the look up, since we do not know whether there has been a new inode created on another node. The look up calls d_splice_alias which then tries to rehash the dentry - so the solution here is to simply check for that in d_splice_alias. The same issue is likely to affect any other cluster filesystem implementing ->atomic_open Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: "J.

Creation of a new inode requires a directory search in order to ensure that we are not trying to create an inode with the same name as an existing one. This was hidden away inside the create_ok() function. In the case that there was an existing inode, and a lookup can be substituted for a create (which is the case with regular files when the O_EXCL flag is not in use) then we were doing a second lookup in order to return the inode. This patch merges these two lookups into one. This can be done by passing a flag to gfs2_dir_search() to tell it to just return -EEXIST in the cases where we don't actually want to look up the inode.

In summary, the symptom is intermittent key events lost after resume on some machines with synaptics touchpad (seems this is synaptics _only_), and key events loss is due to serio port reconnect after psmouse sync lost. Removing psmouse and inserting it back during the suspend/resume process is able to work around the issue, so the difference between psmouse_connect() and psmouse_reconnect() is the key to the root cause of this problem. After comparing the two different paths, synaptics driver has its own implementation of synaptics_reconnect(), and the missing psmouse_probe() seems significant, the patch below added psmouse_probe() to the reconnect process, and has been verified many times that the issue could not be reliably reproduced. There are two PS/2 commands in psmouse_probe(): 1. PSMOUSE_CMD_GETID 2. PSMOUSE_CMD_RESET_DIS Only the PSMOUSE_CMD_GETID seems to be significant. The PSMOUSE_CMD_RESET_DIS is irrelevant to this issue after trying several times. So we have only implemented this patch to issue the PSMOUSE_CMD_GETID so far.

This version has one more correction: the vmalloc calls are replaced by __vmalloc calls to preserve the GFP_NOFS flag. When GFS2's directory management code allocates buffers for a directory hash table, if it can't get the memory it needs, it currently gives a bad return code. Rather than giving an error, this patch allows it to use virtual memory rather than kernel memory for the hash table. This should make it possible for directories to function properly, even when kernel memory becomes very fragmented.

由 Maxim Patlasov 提交于
The bug was introduced with async_dio feature: trying to optimize short reads, we cut number-of-bytes-to-read to i_size boundary. Hence the following example: truncate --size=300 /mnt/file dd if=/mnt/file of=/dev/null iflag=direct led to FUSE_READ request of 300 bytes size. This turned out to be problem for userspace fuse implementations who rely on assumption that kernel fuse does not change alignment of request from client FS. The patch turns off the optimization if async_dio is disabled. And, if it's enabled, the patch fixes adjustment of number-of-bytes-to-read to preserve alignment. Note, that we cannot throw out short read optimization entirely because otherwise a direct read of a huge size issued on a tiny file would generate a huge amount of fuse requests and most of them would be ACKed by userspace with zero bytes read.

If request submission fails for an async request (i.e., get_user_pages() returns -ERESTARTSYS), we currently skip the -EIOCBQUEUED return and drop into wait_for_sync_kiocb() forever. Avoid this by always returning -EIOCBQUEUED for async requests. If an error occurs, the error is passed into fuse_aio_complete(), returned via aio_complete() and thus propagated to userspace via io_getevents().

Fix bug introduced by commit 4582a4ab "FUSE: Adapt readdirplus to application usage patterns". We need to check for a positive dentry; negative dentries are not added by readdirplus. Secondly we need to advise the use of readdirplus on the *parent*, otherwise the whole thing is useless. Thirdly all this is only relevant if "readdirplus_auto" mode is selected by the filesystem. We advise the use of readdirplus only if the dentry was still valid. If we had to redo the lookup then there was no use in doing the -plus version.
