The changes in 195702, 195703, and 195821 prevented a thread from suspending while holding locks inside of NFS by forcing the thread to fail sleeps with EINTR or ERESTART but defer the thread suspension to the user boundary. However, this had the effect that stopping a process during an NFS request could abort the request and trigger EINTR errors that were visible to userland processes (previously the thread would have suspended and completed the request once it was resumed). This change instead effectively masks stop signals while in the NFS client. It uses the existing TDF_SBDRY flag to effect this since SIGSTOP cannot be masked directly. Instead of setting PBDRY on individual sleeps, change the VFS_*() and VOP_*() methods to defer stop signals for filesystems which request this behavior via a new VFCF_SBDRY flag. Note that this has to be a VFC flag rather than a MNTK flag so that it works properly with VFS_MOUNT() when the mount is not yet fully constructed. For now, only the NFS clients set this new flag in VFS_SET(). A few other related changes: - Add an assertion to ensure that TDF_SBDRY doesn't leak to userland. - When a lookup request uses VOP_READLINK() to follow a symlink, mark the request as being on behalf of the thread performing the lookup (cnp_thread) rather than using a NULL thread pointer. This causes NFS to properly handle signals during this VOP on an interruptible mount. - Ignore thread suspend requests due to SIGSTOP if stop signals are currently deferred. This can occur if a process is stopped via SIGSTOP while a thread is running or runnable but before it has set TDF_SBDRY. 2012-04-02T19:06:28Z Mikolaj Golub trociny@FreeBSD.org 2012-04-02T19:06:28Z urn:sha1:e77fbf47a3d9b9dc6299c4384e5b9f7d826a57c7 Make vnode_if.awk parse vnode operations with underscores, like VOP_FOO_BAR.

Replace the multi-line printc statement that outputs all of the #includes with one printc per #include. This allows modules compatible with firmware(9) to be cross-built from a Linux machine without requiring the one true awk to be installed. I've intentionally done the minimal set of changes necessary to make gawk produce valid (but not pretty) C code, to reduce the churn and keep fw_stubs.awk as readable as possible.
