Mark Johnston	7abb0b0922	Don't specify a resid parameter if we're just going to ignore it. Instead, ... let vn_rdwr() check for short reads. MFC after: 3 days Sponsored by: EMC / Isilon Storage Division	2015-02-20 20:49:00 +00:00

Mark Johnston	250246706f	Free the zlib stream after expanding a compressed CTF section. ... Note that this memory would only be leaked once, since CTF info for a kld file is cached after the first access. MFC after: 3 days	2015-02-19 03:29:46 +00:00
Konstantin Belousov	5050aa86cf	Remove the support for using non-mpsafe filesystem modules. ... In particular, do not lock Giant conditionally when calling into the filesystem module, remove the VFS_LOCK_GIANT() and related macros. Stop handling buffers belonging to non-mpsafe filesystems. The VFS_VERSION is bumped to indicate the interface change which does not result in the interface signatures changes. Conducted and reviewed by: attilio Tested by: pho	2012-10-22 17:50:54 +00:00
Konstantin Belousov	526d0bd547	Fix found places where uio_resid is truncated to int. ... Add the sysctl debug.iosize_max_clamp, enabled by default. Setting the sysctl to zero allows to perform the SSIZE_MAX-sized i/o requests from the usermode. Discussed with: bde, das (previous versions) MFC after: 1 month	2012-02-21 01:05:12 +00:00
Ryan Stone	6f6924e5a6	The in-kernel CTF parser caches the result of its first attempt to parse ... CTF data from a module. On subsequent attempts to retrieve CTF data for a module, return an error if there no CTF data. This fixes a panic if you try to enable fbt probes on a module with CTF data twice.
