| | | | | | | | | | | forcedirectio mount This patch fixes an oops reported by Adrian Bunk in cifs_user_read when a null read response is returned on a forcedirectio mount.

| | | | | | | | | | typically - header + 13 pages). Forgetting to set wsize on the mount command costs more than 10% on large write (can be much more) so this makes a saner default. We still shrink this default smaller if server can not support it. Signed-off-by: Steve French <sfrench@us.ibm.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | ICC likes to complain about storage class not being first, GCC doesn't care much (except for cases like "inline static"). have a hard time seeing how it could break anything.

| * [PATCH] Fix and add EXPORT_SYMBOL(filemap_write_and_wait)OGAWA Hirofumi2006-01-082-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch add EXPORT_SYMBOL(filemap_write_and_wait) and use it. See mm/filemap.c: And changes the filemap_write_and_wait() and filemap_write_and_wait_range(). Current filemap_write_and_wait() doesn't wait if filemap_fdatawrite() returns error. However, even if filemap_fdatawrite() returned an error, it may have submitted the partially data pages to the device. (e.g. in the case of -ENOSPC) <quotation> Andrew Morton writes, If filemap_fdatawrite() returns an error, this might be due to some I/O problem: dead disk, unplugged cable, etc. Given the generally crappy quality of the kernel's handling of such exceptions, there's a good chance that the filemap_fdatawait() will get stuck in D state forever. </quotation> So, this patch doesn't wait if filemap_fdatawrite() returns the -EIO. Trond, could you please review the nfs part? Especially I'm not sure, nfs must use the "filemap_fdatawrite(inode->i_mapping) == 0", or not.

* | [CIFS] Allow local filesize for file that is open for write to be updatedSteve French2006-01-122-2/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | from server when mount forcedirectio. Allowing update of file size with non forcedirectio mounts should be allowed in the fiture but requires carefully writing out the last page in the local file if it is a partial page in order to avoid corruption and careful serialization Thanks to Maximiliano Curia who suggested similar changes and provided a testcase.

* | [CIFS] Fix cifs trying to write to f_opsSteve French2006-01-081-6/+11
| | | | | | | | | | | | | | | | | | | | | | | | patch 2ea55c01e0c5dfead8699484b0bae2a375b1f61c fixed CIFS clobbering the global fops structure for some per mount setting, by duplicating and having 2 fops structs. However the write to the fops was left behind, which is a NOP in practice (due to the fact that we KNOW the fops has that field set to NULL already due to the duplication). So remove it... In addition, another instance of the same bug was forgotten in november. Signed-off-by: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Steve French <sfrench@us.ibm.com>

This is Christoph's patch merged with the new nobrl file operations Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> From: Christoph Hellwig <hch@lst.de> - support vectored and async aio ops unconditionally - this is above the pagecache and transparent to the fs - remove cifs_read_wrapper. it was only doing silly checks and calling generic_file_write in all cases. - use do_sync_read/do_sync_write as read/write operations. They call ->readv/->writev which we now always implemente. - add the filemap_fdatawrite calls to writev/aio_write which were missing previously compared to plain write. no idea what the point behind them is, but let's be consistent at least..

* [CIFS] Change pragma pack(1) to attribute(packed) to allow cifs on arm to accessSteve French2005-10-273-186/+182
| | | | | | | | | | | | | | | | | unaligned structures coming in off the wire gcc on arm processors generates very odd code with pragma pack specified - although it does pack the structures in some sense - it does not allow you to access unaligned elements in nested structures at the right offset as other architectures do. Oddly enough though, specifying the structures as packed the long way - one by one with the packed attribute does work. Rather than fighting over whether this is a gcc bug or some obscure side effect of pragma pack, it is easier to do what most (all but 96 other places in the kernel) do - and replace pragma pack with dozens of attribute(packed) structure qualifiers. Much more verbose ... but at least it works.
