2005-05-01[PATCH] aio: remove superfluous kiocb member initializationKen Chen1-10/+1
This patch removes superfluous kiocb member initialization in the AIO allocation and deallocation path. For example, in really_put_req(), right before kiocb is returned to slab, 5 variables are reset to NULL. The same variables will be initialized at the kiocb allocation time, so why bother reset them knowing that they will be set to valid data at alloc time? Another example: ki_retry is initialized in __aio_get_req, but is initialized again in io_submit_one.

2005-05-01[PATCH] convert that currently tests _NSIG directly to use valid_signal()Jesper Juhl1-1/+2

2005-05-01[PATCH] reiserfs: make resize option auto-get new device sizePaolo 'Blaisorblade' Giarrusso1-7/+14
It's trivial for the resize option to auto-get the underlying device size, while it's harder for the user. I've copied the code from jfs. Since of the different reiserfs option parser (which does not use the superior match_token used by almost every other filesystem), I've had to use the "resize=auto" and not "resize" option to specify this behaviour. Changing the option parser to the kernel one wouldn't be bad but I've no time to do this cleanup in this moment. Btw, the mount(8) man page should be updated to include this option. Cc the relevant people, please (I hope I cc'ed the right people).

2005-05-01[PATCH] procfs: Fix hardlink counts for /proc/<PID>/taskDaniel Drake1-2/+6
The current logic assumes that a /proc/<PID>/task directory should have a hardlink count of 3, probably counting ".", "..", and a directory for a single child task. It's fairly obvious that this doesn't work out correctly when a PID has more than one child task, which is quite often the case.

2005-05-01[PATCH] procfs: Fix hardlink countsDaniel Drake1-2/+10
The pid directories in /proc/ currently return the wrong hardlink count - 3, when there are actually 4 : ".", "..", "fd", and "task". This is easy to notice using find(1): cd /proc/<pid> find In the output, you'll see a message similar to: find: WARNING: Hard link count is wrong for .: this may be a bug in your filesystem driver. Automatically turning on find's -noleaf option. Earlier results may have failed to include directories that should have been searched. http://bugs.gentoo.org/show_bug.cgi?id=86031 I also noticed that CONFIG_SECURITY can add a 5th: attr, and performed a similar fix on the task directories too.

2005-05-01[PATCH] uml - hostfs: avoid buffersPaolo 'Blaisorblade' Giarrusso1-1/+1
Use this: .set_page_dirty = __set_page_dirty_nobuffers, We already dropped the inclusion of <linux/buffer_head.h>, and we don't have a backing block device for this FS. "Without having looked at it, I'm sure that hostfs does not use buffer_heads. So setting your ->set_page_dirty a_op to point at __set_page_dirty_nobuffers() is a reasonable thing to do - it'll provide a slight speedup." This speedup is one less spinlock held and one less conditional branch, which isn't bad.

2005-05-01[PATCH] drop_buffers() oops fixakpm@osdl.org1-1/+1
In rare situations, drop_buffers() can be called for a page which has buffers, but no ->mapping (it was truncated, but the buffers were left behind because ext3 was still fiddling with them). But if there was an I/O error in a buffer_head, drop_buffers() will try to get at the address_space and will oops.

2005-04-29[AUDIT] LOGIN message credentialsSteve Grubb1-1/+1
Attached is a new patch that solves the issue of getting valid credentials into the LOGIN message. The current code was assuming that the audit context had already been copied. This is not always the case for LOGIN messages. To solve the problem, the patch passes the task struct to the function that emits the message where it can get valid credentials.

2005-04-29namei: add audit_inode to all branches in path_lookupPrasanna Meda1-8/+12
Main change is in path_lookup: added a goto to do audit_inode instead of return statement, when emul_lookup_dentry for root is successful.The existing code does audit_inode only when lookup is done in normal root or cwd. Other changes: Some lookup routines are returning zero on success, and some are returning zero on failure. I documented the related function signatures in this code path, so that one can glance over abstract functions without understanding the entire code.
