src/config/kernel-insert-inode-locked.m4, branch zfs-0.6.2 FreeBSD source tree When checking for symbol exports, try compiling. 2012-07-26T20:42:57+00:00 Etienne Dechamps etienne.dechamps@ovh.net 2012-07-25T21:38:58+00:00 705741827ab55e7d92c3eb74f332a5ddd24971b5 This patch adds a new autoconf function: ZFS_LINUX_TRY_COMPILE_SYMBOL. This new function does the following: - Call LINUX_TRY_COMPILE with the specified parameters. - If unsuccessful, return false. - If successful and we're configuring with --enable-linux-builtin, return true. - Else, call CHECK_SYMBOL_EXPORT with the specified parameters and return the result. All calls to CHECK_SYMBOL_EXPORT are converted to LINUX_TRY_COMPILE_SYMBOL so that the tests work even when configuring for builtin on a kernel which doesn't have loadable module support, or hasn't been built yet.

This patch adds a new autoconf function: ZFS_LINUX_TRY_COMPILE_SYMBOL.
This new function does the following:

 - Call LINUX_TRY_COMPILE with the specified parameters.
 - If unsuccessful, return false.
 - If successful and we're configuring with --enable-linux-builtin,
   return true.
 - Else, call CHECK_SYMBOL_EXPORT with the specified parameters and
   return the result.

All calls to CHECK_SYMBOL_EXPORT are converted to
LINUX_TRY_COMPILE_SYMBOL so that the tests work even when configuring
for builtin on a kernel which doesn't have loadable module support, or
hasn't been built yet.

Issue #851
Linux 2.6.28 compat, insert_inode_locked() 2011-03-22T19:15:54+00:00 Brian Behlendorf behlendorf1@llnl.gov 2011-03-22T16:55:09+00:00 bdf4328b04544ac3759d689d0a68e514b6df1025 Added insert_inode_locked() helper function, prior to this most callers used insert_inode_hash(). The older method doesn't check for collisions in the inode_hashtable but it still acceptible for use. Fallback to using insert_inode_hash() when insert_inode_locked() is unavailable.
