Lines Matching full:busy

103  * Search for a busy extent within the range of the extent we are about to
104  * allocate.  You need to be holding the busy extent tree lock when calling
105  * xfs_extent_busy_search(). This function returns 0 for no overlapping busy
106  * extent, -1 for an overlapping but not exact busy extent, and 1 for an exact
148  * The found free extent [fbno, fend] overlaps part or all of the given busy
149  * extent.  If the overlap covers the beginning, the end, or all of the busy
151  * allocation.  We can't split a busy extent because we can't modify a
152  * transaction/CIL context busy list, but we can update an entry's block
186 	 * If there is a busy extent overlapping a user allocation, we have  in xfs_extent_busy_update_extent()
206 		 * We would have to split the busy extent to be able to track  in xfs_extent_busy_update_extent()
208 		 * modify the list of busy extents attached to the transaction  in xfs_extent_busy_update_extent()
211 		 * Force out the log to clear the busy extent and retry the  in xfs_extent_busy_update_extent()
244 		 * The busy extent is fully covered by the extent we are  in xfs_extent_busy_update_extent()
247 		 * tracking busy extents in the transaction or CIL context,  in xfs_extent_busy_update_extent()
250 		 * We also need to restart the busy extent search from the  in xfs_extent_busy_update_extent()
343  * For a given extent [fbno, flen], search the busy extent list to find a
344  * subset of the extent that is not busy.  If *rlen is smaller than
348  * Return the current busy generation for the group if the extent is busy. This
349  * value can be used to wait for at least one of the currently busy extents
350  * to be cleared. Note that the busy list is not guaranteed to be empty after
483 			 * allocation;  if the segment is no longer busy at  in xfs_extent_busy_trim()
485 			 * even if it is still busy, we will get a forward  in xfs_extent_busy_trim()
557  * Remove all extents on the passed in list from the busy extents tree.
596  * Flush out all busy extents for this group.
598  * If the current transaction is holding busy extents, the caller may not want
599  * to wait for committed busy extents to resolve. If we are being told just to
600  * try a flush or progress has been made since we last skipped a busy extent,
604  * in the transaction busy list and the log force won't resolve that situation.
606  * caller it needs to commit the busy extents it holds before retrying the
624 	/* Avoid deadlocks on uncommitted busy extents. */  in xfs_extent_busy_flush()
636 	/* Wait for committed busy extents to resolve. */  in xfs_extent_busy_flush()
680  * Callback for list_sort to sort busy extents by the group they reside in.
